The Time Library contains functions and type definitions for time calculations in the UNIX time for-
mat which counts the number of seconds since the "epoch". This is very convenient for programs
that work with time intervals: the difference between two UNIX time values is a real-time differ-
ence measured in seconds.

What is the epoch?
Originally it was defined as the beginning of 1970 GMT. ( January 1, 1970 Julian day ) GMT,
Greenwich Mean Time, is a traditional term for the time zone in England.

The TimeStruct type is a structure type suitable for time and date storage.

- Time_dateToEpoch 
- Time_epochToDate 
- Time_datediff

function Time_dateToEpoch(var ts : TimeStruct) : longint;

Number of seconds since January 1, 1970 0h00mn00s.

This function returns the UNIX time : number of seconds since January 1, 1970
0h00mn00s.

Parameters : 

- 

ts

: time and date value for calculating UNIX time. 

Nothing.

var ts1 : TimeStruct;

Epoch : longint;

...
// what is the epoch of the date in ts ?

epoch := Time_dateToEpoch(ts1) ;
