That sounds like the UNIX epoch or, at least, one hour from the UNIX
epoch (the UNIX epoch in the Western European time zone?).

Perhaps the Windows 98 version of "mktime()" is failing? Or perhaps
the "strptime()" we supply is screwing up on Windows 98?

Check to see what happens after the "strptime()" call in
"parse_preamble()" - print out the members of the "timecode" structure,
to make sure the day/month/year/hour/minute/second values are set
appropriately (for example, for "22/11/2001 20:03:24.4375", that's
timecode.tm_sec: 24
timecode.tm_min: 3
timecode.tm_hour: 20
timecode.tm_mday: 22
timecode.tm_mon: 10
timecode.tm_year: 101 (2001-1900)
If they are, make sure that the return value from "strptime()" is
non-null, and that the result of "mktime()" isn't 0 or -1.
