As easy to parse time format, I'd rather suggest seconds or microseconds since 1970 (1970 is the time base of the Unix time stamp, so this is referring to POSIX) - microseconds that's what Gforth's utime gives you. For a file time stamp, seconds are probably good enough, for other purposes, you want microseconds. This is much easier to parse (it's just a 32 or 64 bit number), it's easy to calculate differences, and to convert it into a time&date string is also not too difficult. I've put some code here, this is correct until around 30 BC, when the Julian calendar was in place, and the obvious bugs were fixed (by that time, they had already shifted the year by 3 days, so 24th of december was no longer winter solstice). http://www.forth-ev.de/wiki/doku.php/examples:daymonthyear I do not want a human readable time format in a Forth program as primitive data type. If you want it human readable, implement something like >utime and .utime (>utime would leave it in the picture number buffer). The proposed word would be file-utime ( addr u -- udc uda udu ), with three result values, because you might want create, access and modification time. -- Bernd Paysan "If you want it done right, you have to do it yourself" http://bernd-paysan.de/
