Epochs and Unix Time
An epoch is a period of time identified by a starting point.
The standard epoch for measuring against is known colloqially as "Unix Time": midnight on 1st January 1970. Unix time is the number of seconds that have elapsed since this point. This is the standard for Windows and most unix systems.
For example midnight on 2nd January 1970 would be 86400 seconds since the epoch. The deduction is as follows:
60 * 60 * 24 = 86400
We are multiplpying the number of seconds in a minute by the number of minutes in an hour by the number of hours in a day.
