Having only recently joined the list, I never saw the original emails. But,
after digging them up from the archives ...

An alternative method would be to listen for a suspend (or resume) and
somehow either
 a) reset gtod::inited to FALSE. gtod::prime runs on next call of
gettimeofday
 b) call gtod::prime() immediately (on resume)

However, both mean making the local static variable gtod visible at a higher
level (or provision of an interface for the reset)

I believe the relevant windows message to look for is WM_POWERBROADCAST
(PBT_APMSUSPEND, PBT_APMRESUMESUSPEND). While you're there, you might as
well listen for WM_TIMECHANGE to handle base time changes.

Not being familiar with cygwin source, I can't say where this would go
(assuming cygwin pays attention to windows messages). Also suspend
consistently crashes all the windows boxes I have used, so I can't really
test this.


Dave.
