On one hand Windows has Filetime, and we work in Windows.
On the other hand 'ux time is used/supported as "standard".
On the gripping hand, maybe it is the 'ux that should upgrade to be compatable:
"What happens on January 19, 2038?
On this date the Unix Time Stamp will cease to work due to a 32-bit overflow. Before this moment millions of applications will need to either adopt a new convention for time stamps or be migrated to 64-bit systems which will buy the time stamp a "bit" more time."
"Systemtime range and practical limit of filetime 1 January 1601 to 14 September 30828, 02:48:05.4775807"
Filetime will last 15 times more years remaining, epoch earlier, and 10^7 times better resolution.
Another Motie, eh?
Unix Timestamp will only "cease to work" i.e. overflow if it is calculated/represented as a LONG. Use a DWORD instead and you get another 68 years.
The UnixTimeNowStr above has the same maximum 14 September 30828 upper limit as FileTime
Many systems are already using an Int64 and I doubt the there will be many systems still using an int32 in 12 years time.
Use a Quad and you get over 282 billion years
That should be enough for Eric's "cosmologist working on the age of the universe,"
