What does Epoch time represent?
In a computing context, an epoch is the date and time relative to which a computer’s clock and timestamp values are determined.

What is epoch time in Java?

Why is there no October in 2038?
The year 2038 problem is caused by 32-bit processors and the limitations of the 32-bit systems they power. The processor is the central component that drives all computers and computing devices.
How do I check my epoch time?
You can find the current epoch time with the following Unix command:
- $ date +%s 1010705782. You can print the Unix epoch time of a particular time string as follows.
- $ date -d ‘Sat Sep 8 18:46:39 PDT 2001’ +%s 999999999. That same epoch time in a different time zone:
- $ date -d ‘Sun Sep 9 01:46:39 UTC 2001’ +%s 999999999.
