Timestamp in Unix

In 1969, at the onset of the technological revolution, Unix engineers recognized the urgent necessity for a clock capable of calculating coordinated universal time. To address this, they employed programming languages to calculate all milliseconds that elapsed from a specific reference point. The challenge was determining when to initiate the timer.

All engineers involved in the project unanimously agreed that the Unix time would commence its count on January 1, 1970. The Unix epoch precisely commenced at ‘1970 01 01t00 00’ in Unix time format. When converted into a standard date format, it corresponds to January 1, 1970, at 00:00:00, marking the initiation of the Unix timestamp with a value of 0, including the fractional part.

Representing your date and time in the format of random binary digits like ‘1970 01 01t00 00’ can be cumbersome, which is why software exists to convert Unix time into a human-readable date and time.


Now that you understand the historical significance of Unix timestamps, you may be curious about their actual function. To provide context, prior to Unix timestamps, each operating system had its unique way of representing time and date.

While this may not appear as a significant issue on an individual system, the broader challenge arose when data needed to be shared across diverse platforms. Inconsistent date and time values, along with varied date and time functions, led to significant problems.

To address these challenges, the Unix timestamp was introduced. For instance, it calculated hours, seconds, milliseconds, microseconds, and even nanoseconds. These calculations persist to this day, as the timer continuously tracks time and date. However, it’s important to note that the Unix timestamp currently does not account for leap seconds, as it follows the epoch time of leap years.

The Unix Issue

Since the inception of the Unix timestamp in the 1970s, during the early stages of the technological revolution, it was initially designed to handle a 32-bit integer number format. This meant that when the timer reached 2,147,483,647 seconds, it would reset back to 1901.

The scheduled reset was set to occur on January 19, 2038. This posed a challenge as many legacy software systems were designed to work exclusively with the 32-bit number format. Fortunately, a solution was found by converting the software to handle 64-bit integers, effectively resolving the impending problem.

How to Calculate a Timestamps Using Unix

Calculating a Unix timestamp involves determining the seconds that have elapsed between a chosen date and time and the Unix epoch (January 1, 1970, at 00:00:00 UTC). Here’s a step-by-step guide:

  1. Select Date and Time: Choose the specific date and time for which you want to calculate the Unix timestamp. The chosen date should be after January 1, 1970, as that marks the starting point of the Unix timer. Include the year, month, day, hour, minute, and even the second. Ignore leap seconds, as the Unix timestamp doesn’t consider them.

  2. Convert to UTC: Unix timestamps are based on Coordinated Universal Time (UTC). If the selected date and time are not already in UTC, convert them to UTC. You don’t need to account for time zone offsets or daylight saving adjustments; our server will handle these automatically.

  3. Calculate the Difference: Determine the difference in milliseconds between the chosen date and time and the Unix epoch (January 1, 1970, at 00:00:00 UTC). You can perform this calculation using programming commands or tools. Alternatively, our VPS servers offer a convenient feature to convert the Unix time format into a readable date.

Value of Unix Time on a VPS Server

  • After tracing the evolution from epoch Unix time to our current technologically advanced era, you might be pondering how the Unix timestamp aligns with a VPS Server.

Much like Unix time and date are integral to software globally, they hold significant importance for our server as well. Our VPS hosting server, in line with virtually advanced servers, adheres to the Unix time format. You have the flexibility to adjust your epoch time and dates, ranging from an hour to several hours, based on your preferences.

Given the importance of coordinated universal time and dates, our system places a high value on Unix timestamps. To underscore their significance, let’s explore a few reasons why Unix timestamps are crucial to the functionality of our server:

  • Ensuring Data Consistency:

    Consistency stands out as a crucial factor driving the necessity for Unix time and date functions. All computer systems, servers, and the software they operate must synchronize with one another.

    Before the advent of the Unix timestamp, diverse computer systems and programming languages had their proprietary methods of representing dates. This lack of standardization posed challenges in sharing and manipulating time-related data across different systems.

    When a specific date and time format is confined to a single server and varies across platforms, data consistency is compromised. In contrast, the current Unix time number facilitates consistent data exchange across all servers. As our server automatically aligns with your local timezone, concerns about data inconsistencies are alleviated.

  • Enhanced Operational Efficiency:

    The Unix timestamp continuously tracks the seconds elapsed since January 1, 1970, providing a numerical representation of time and date. Despite the representation of Unix time in numerical forms like ’01 01t00 00′, there’s no need for concern. Our software automatically translates this date and time into a human-readable format, making it easily understandable.

    Since the Unix epoch, we’ve been able to precisely identify a specific date and time without the need to delve into historical records. Calculating a timestamp on Unix or Linux and converting it is a straightforward process.

    Furthermore, storing and parsing data in the form of integers significantly enhances efficiency in both memory and storage. Representing time as a single integer streamlines calculations and comparisons involving date and time.

    Performing arithmetic operations on a single numeric value is more efficient and straightforward compared to handling various components of date and time separately. This streamlined approach contributes to increased operational efficiency.

  • Maintaining Server Events:

    With the current Unix timestamp accurately reflecting the current date in UTC time, maintaining your server becomes more straightforward. Many server updates, bug fixes, and other patches are scheduled based on specific dates aligned with your local time and dates. Properly postponing these updates relies on the server tracking the cumulative Unix milliseconds.

    Servers generate diverse logs to record events, errors, and activities. These logs typically include a timestamp to indicate the occurrence time of each event. The Unix timestamp ensures uniformity in event timestamps across various logs. The time intervals between each log are also separately monitored to identify and address any potential errors. This meticulous approach aids in the effective management of server events.

  • Cross-Platform Compatibility:

    Linux or Unix timestamps enjoy broad support across diverse operating systems and programming languages. Our servers synchronize your time zone with UTC time, ensuring compatibility across systems. Seamless server compatibility is vital for efficient data transfer across multiple servers.

    It’s crucial to dispel the misconception that a server stops counting time when temporarily powered off. In reality, the physical hardware of any server is equipped with an embedded battery, enabling the time count even when the server is powered down.

    Servers adhering to the Unix time number system meticulously track hours, seconds, milliseconds, microseconds, and even nanoseconds.

    If desired, you can easily adjust your server’s timezone. A simple command to your server specifying the preferred timezone allows the server to make the necessary adjustments. This flexibility enhances user control over time settings.

  • Task Scheduling:

    Numerous computer systems and applications rely on logging events, scheduling tasks, and maintaining chronological order. The number of seconds elapsed determines the sequence of actions to be executed. The Unix timestamp serves as a precise and standardized method for managing such tasks.

    Server maintenance tasks, including updates, backups, and cleanups, are often scheduled to occur at specific times. The Unix timestamp plays a crucial role in accurately scheduling these tasks, ensuring their execution at the designated times irrespective of the server’s location or time zone.

    For instance, if you have tasks or jobs scheduled based on specific times, altering the time zone could impact when these tasks run. It’s essential to review and adjust any scheduled tasks to align with the new time zone.

    While some servers may encounter difficulties following two time zones, our server seamlessly aligns with your local time. This approach eliminates unnecessary complications for our users, as the Unix time easily converts into a human-readable date and time. This conversion was implemented to make timestamps more accessible, as the binary code representation was not user-friendly for non-programmers.


With a comprehensive understanding of the Unix epoch time format and the process of converting elapsed date and time into a readable format, you are well-equipped to manage your server effectively. Understanding the relationship between Unix timestamps and VPS servers is essential for effective server maintenance.

Although the timestamp might not take leap seconds into consideration, its format is crucial for both your server and the software that is integrated into each of your applications. Through the utilisation of the Unix timestamp, developers can maintain a dependable and effective virtual private server environment. When used properly, this timestamp can act as the engine of your server.
