I am not exactly sure if this is correct, so was hoping that someone could take a look at this math and see if I have it wrong, or perhaps there is a more efficient way of doing it. Converting epoch time to @dateformat() time-value:

Code:
REM Epoch for Jan 3, 03 - 02:19:17
%%epoch = 1073096357

REM Years since 1900 (windows) to 1970 (Unix)
%%fadd = 25569

%%vdsDate = @fadd(%%fadd,@fmul(@fdiv(@fdiv(@fdiv(@fdiv(%%epoch,365),24),60),60),365))

info Epoch date %%epoch is: @datetime(mmmm dd@chr(44) yyyy hh:nn:ss,%%vdsDate)

It certainly could be one way of doing this piece of math. I can see nothing wrong with it, except that
the variable %t in your %%vdsDate calc should be %%epoch, of course.

BTW. This conversion to/fro UNIX date/time values is also in my TimeDate.dll
