 Return value is hours * 3600 + minutes * 60 + seconds in UTC.
 The underlying function in the XTRA is GetSystemTime:
	https://learn.microsoft.com/en-us/windows/win32/api/sysinfoapi/nf-sysinfoapi-getsystemtime

 Safecrackers only needs the number of seconds since the start of the game.
 Since not all platforms that run ScummVM have a clock, it's implemented as
 the number of seconds since the start of ScummVM.
