A library for calculating UNIX-like timestamps for dates AFTER January 1, 1970 or January 1 of whichever year is selected as EPOCH. This library allows to generate 32 bits timestamps that are compatible with valid current UNIX timestamps for the time period between 1/1/1970 and 2/7/2106 06:28:15. Now it also allows to generate custom timestamps specifying the EPOCH year.
