Re: ISO-8601 dates and issue 614

You will find an interesting platform dependency here. There are lots of
Windows/CVS complaints about file modification date changes when a system
switches from standard to daylight savings time and back. In fact (ahem)
most versions of Windows seem to write the modification date to the disk as
UTC. This means that when the user changes time zones, or moves from or to
daylight savings, the file modification times appear to change when in fact
the OS is reporting an accurate date. The many rants against Windows and
suggestions that that this is a "bug" suggest that most Unix based systems
write local time to the disk.

It's also a problem since Windows is inconsistent. Win95 appears to write
local time to the disk, whereas WinNT and Win2000 write UTC.

I'm not sure how deep the implications of these differences is, but though
I'd make you aware of them just in case.
