Date to Unix Timestamp
What is the unix timestamp?
A Unix timestamp is a numerical representation of a specific moment in time, usually expressed as the number of seconds that have elapsed since January 1st, 1970 at 00:00:00 UTC. This system of tracking time is widely used in computer systems, particularly in Unix-based operating systems and web development. The Unix timestamp provides a simple way to represent and compare dates and times, as well as perform arithmetic operations with time data.
|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?
On January 19, 2038 at 3:14:07 UTC, the 32-bit Unix timestamp will reach the maximum value it can store, which is 2^31-1 (or 2147483647 in decimal).
This is known as the "Year 2038 problem". At this point, the timestamp will "wrap around" to a negative number, causing problems with software and systems that store or process time as a 32-bit Unix timestamp.
This may lead to incorrect or unexpected results in various systems, such as file timestamps, system logs, and expiration dates.
It's important to note that many modern systems now use 64-bit timestamps, which will not be affected by the Year 2038 problem and can represent dates far beyond 2038. However, some older systems and software may still be vulnerable and may need to be updated to handle timestamps correctly beyond 2038.
