1. read/write file timestamp
How does one read the epoch time for a file in Eu on windoze, and then
apply that timestamp to another file? I know dir() lists the time and date, but
that's not epoch time, and it doesn't write a new timestamp or other
attributes to a file. Win32lib has a attribute set for hidden, system,
compressed, etc, but not time/date ?

Use the Windows API functions GetFileTime and SetFileTime in kernel32.dll
to read and write file timestamps.
I think you must convert the "Windows time" from/to epoch time yourself,
here is some information (there seem to be different "epoch times"):

You can use datetime.e
-- DateTime.e - Routines for handling Date and Time - (c) 2001 CyrekSoft --
Use secondsDifference() function, like this:
d = dir(...)
epoch = secondsDifference({{1970,1,1},{0,0,0}},{
{d[1][D_YEAR],d[1][D_MONTH],d[1][D_DAY]},
{d[1][D_HOUR],d[1][D_MINUTE],d[1][D_SECOND]}})

Kat,
I don't think Windows has a concept of epoch time. The files times are stored as
a 64-bit value representing the number of 100-nanosecond intervals since January
1, 1601.
And there is no API to change the datetimes (that I know of).

There actually is. I just remembered, that I already had published it.
Sorry Kat, I didn't think of it, when I replied the first time.
(Things like this sometimes happen, when one gets older...)
Go to http://home.arcor.de/luethje/prog/ and get the file 'mbox100.zip'.
It comes with the Euphoria source code. Look at 'winfile.e'.
