Linux timestamp to date online

Timestamp To Date Converter

Timestamp Online is timestamp converver between unix timestamp and human readable form date. If you want to convert timestamp, it is sufficient to either enter your timestamp into input area, or you can construct URL with your timestamp — http://timestamp.online/timestamp/ .

Timestamp Online also supports countdown, so you can see, how much time remains to particular timestamp. URLs for countdowns have following form — http://timestamp.online/countdown/ .

Current Timestamp Examples

These examples are showing how to get current unix timestamp in seconds. These examples are returning timestamp in seconds, although some of the languages are returning timestamp in milliseconds.

long ts = System.currentTimeMillis()/1000;

Current Date and Time Examples

These examples are showing how to get current date and time that could be presented to the end-user.

These examples are showing how to parse date in human readable form to unix timestamp in either milliseconds or seconds.

Date.parse("2023-07-14 05:35:29")/1000;

import time int(time.mktime(time.strptime("2023-07-14 05:35:29"))) - time.timezone

import java.text.SimpleDateFormat; SimpleDateFormat dateFormat = new SimpleDateFormat("YYYY-MM-dd HH:mm:ss") long ts = dateFormat.parse(2023-07-14 05:35:29).getTime()/1000;

Unix Time

Unix time (also known as POSIX time or Epoch time) is a system for describing instants in time, defined as the number of seconds that have elapsed since 00:00:00 Coordinated Universal Time (UTC), Thursday, 1 January 1970, not counting leap seconds. It is used widely in Unix-like and many other operating systems and file formats. Because it does not handle leap seconds, it is neither a linear representation of time nor a true representation of UTC.

What is epoch time?

The Unix epoch (or Unix time or POSIX time or Unix timestamp) is the number of seconds that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap seconds (in ISO 8601: 1970-01-01T00:00:00Z). Literally speaking the epoch is Unix time 0 (midnight 1/1/1970), but ‘epoch’ is often used as a synonym for Unix time. Some systems store epoch dates as a signed 32-bit integer, which might cause problems on January 19, 2038 (known as the Year 2038 problem or Y2038). The converter on this page converts timestamps in seconds (10-digit), milliseconds (13-digit) and microseconds (16-digit) to readable dates.

Thanks to everyone who sent me corrections and updates!

Please note: All tools on this page are based on the date & time settings of your computer and use JavaScript to convert times. Some browsers use the current DST (Daylight Saving Time) rules for all dates in history. JavaScript does not support leap seconds.

Epoch & Unix Timestamp Conversion Tools

Unix time (also known as Epoch time, POSIX time,seconds since the Epoch,or UNIX Epoch time) is a system for describing a point in time. It is the number of seconds that have elapsed since the Unix epoch, minus leap seconds; the Unix epoch is 00:00:00 UTC on 1 January 1970 (an arbitrary date); leap seconds are ignored,with a leap second having the same Unix time as the second before it, and every day is treated as if it contains exactly 86400 seconds. Due to this treatment Unix time is not a true representation of UTC.

Human Readable Time	Seconds
1 Hour	3600 Seconds
1 Day	86400 Seconds
1 Week	604800 Seconds
1 Month (30.44 days)	2629743 Seconds
1 Year (365.24 days)	31556926 Seconds

What happens on January 19, 2038?

The Year 2038 problem (also called Y2038, Epochalypse, Y2k38, or Unix Y2K) relates to representing time in many digital systems as the number of seconds passed since 00:00:00 UTC on 1 January 1970 and storing it as a signed 32-bit integer. Such implementations cannot encode times after 03:14:07 UTC on 19 January 2038. Similar to the Y2K problem, the Year 2038 problem is caused by insufficient capacity used to represent time.

The latest time since 1 January 1970 that can be stored using a signed 32-bit integer is 03:14:07 on Tuesday, 19 January 2038 (231-1 = 2,147,483,647 seconds after 1 January 1970). Programs that attempt to increment the time beyond this date will cause the value to be stored internally as a negative number, which these systems will interpret as having occurred at 20:45:52 on Friday, 13 December 1901 (2,147,483,648 seconds before 1 January 1970) rather than 19 January 2038. This is caused by integer overflow, during which the counter runs out of usable digit bits, and flips the sign bit instead. This reports a maximally negative number, and continues to count up, towards zero, and then up through the positive integers again. Resulting erroneous calculations on such systems are likely to cause problems for users and other reliant parties.
