Happy GNU Year! Unix Timestamp 1,500M – Friday, July 14 02:40 GMT
Happy GNU year! The Unix Timestamp 1500000000 was today at 02:40 UTC/GMT.
It is an interesting marker that is happening today at 2:40 GMT the Unix timestamp will be 1500000000.
The Unix timestamp, otherwise known as POSIX time or the number of seconds since the Unix epoch, is a system which makes it easy to identify and describe a single instant or instants in time. It works by simply counting the number of seconds that have elapsed since Thursday, January 1st, 1970 at midnight (00:00:00 Coordinated Universal Time UTC/GMT).
Used universally in Unix-like operating systems plus extensively in file formats and even now often databases. Although, leap seconds are not counted because they can refer to two distinct, separate instants around the leap second.
You can check the Unix time on most Unix systems by typing the following command into a terminal. This command is to print or set the time.

At 01:46:40 UTC on Sunday, 9 September 2001, was the Unix billennium (Unix time number 1,000,000,000). Notable significant moments in Unix time are commonly round numbers.
Have you had your coffee today? Then you’ve probably realise that there are some issues with storing time as a Unix timestamp. If you’re interested in learning more about time and how many programmers can come to hate time and time zones, we highly recommend the extremely accessible and entertaining video The Problem with Time & Timezones on the Computerphile YouTube channel, starring Tom Scott.
Lastly, if you watch the video, to add to the doom often Unix timestamps are stored as 32-bit numbers. Unfortunately, the 32-bit representation of a Unix timestamp will run out of space. This is set to happen on the 19th of January 2038 (03:14:07 GMT). This is referred to as “The year 2038 problem”. A which point if anyone is still using a 32-bit storage mechanism at that time, it will overflow and will take the actual count into a negative. Many people believe this to be worse than the Year 2000 bug. Thankfully, we have plenty of time to deal with it.
