What Is A Timestamp?

PHP uses UNIX Timestamp’s for all of it’s date/time functions such as date(), time() and strtotime(). UNIX Timestamp is an integer of the current second since the Unix Epoch which started on . It should be mentioned that this timestamp technically does not change no matter where you are located on the globe, this makes the UNIX Timestamp especially useful for computer systems for tracking and sorting dated information online and in desktop applications.


UNIX Time-stamp 32-bit Limit

Unfortunately most systems and applications around the globe are still using 32-bit systems or 32-bit name-spaces for timestamps, this forces the UNIX Time-stamp to a hard limit of 2147483647, this translates to . Once we go over this number the time-stamp will become invalid and the only way to get around this is to convert to 64-bit which will provide us with a hard date limit of which you might think is good enough forever!
