Public Service Announcement: Daylight Saving Time ends in most parts of the United States this weekend.
Windows 98/98/Me recorded the date and time at which Setup was run in the registry under HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion as a binary value named FirstInstallDateTime. What is the format of this data?
Take the binary value and treat it as a 32-bit little-endian value. The format of the value is basically DOS date/time format, except that the seconds are always 0 or 1 (usually 1), due to a programming error.
Exercise: What error would result in the seconds always being 0 or 1 (usually 1)?

[Update: Falcon is the first to post the correct answer.]
