epoch Prime

Code:

epoch(Date, Time, timezone)

to get current date and time, and to choose only his time zone.

That's the way I would have done it myself. ;-)

I don't see the need for a special epoch(now) function if there is a general epoch(dat, tim, zone) function where the first two parameters can easily be set to the current date and time. And maybe sometime the Prime OS will feature a global timezone variable as well.

The comment should say that "zone" is the timezone relative to UTC in hours. Currently the comment only says that 0 means UTC.

There is a line that may not always work properly: IF tim<>Time THEN tim:=HMS→(tim); END;
This checks if the given parameter equals the current time or not (this decides whether a HMS conversion is required or not). What if both differ by a fraction of a second? Or a second?
I think it's a better idea to advise the user to call the function with →HMS(Time) so that the time parameter always (!) has to be specified in the same hh.mmss format.

And finally... you may have confused "e.g." and "i.e.".

Otherwise it looks fine to me.
