#define	FILETIME_1970 0x019db1ded53e8000
	100ns intervals between 1/1/1601 and 1/1/1970 as reported by SystemTimeToFileTime()

#define	ONE_SECOND ((long)1000000)

Functions
timeval	fromsystime (const SYSTEMTIME &st)
	Convert from UTC system time to Unix time scale (UTC form 01/01/70)

void	tosystime (const timeval &tv, SYSTEMTIME *st)
	Convert from timeval format to SYSTEMTIME format.

timeval	zone_bias ()
	Return time zone bias.

void	tolocaltime (const timeval &tv, SYSTEMTIME *st)
	Convert to local time (in a SYSTEMTIME structure)

void	normalize (timeval &tv)
	Following an arithmetic operation, brings timeval structure to a canonical form where tv_usec is less than 1000000 and has the same sign as tv_sec member.
