It's not clear to me how we could get this into something we can deal
with like gettimeofday.
I looked at the Apache APR project, and they have a routine that returns
the microseconds since 1970 for Unix:
/* NB NB NB NB This returns GMT!!!!!!!!!! */
APR_DECLARE(apr_time_t) apr_time_now(void)
{
struct timeval tv;
gettimeofday(&tv, NULL);
return tv.tv_sec * APR_USEC_PER_SEC + tv.tv_usec;
}
and for Win32:
APR_DECLARE(apr_time_t) apr_time_now(void)
{
LONGLONG aprtime = 0;
FILETIME time;
#ifndef _WIN32_WCE
GetSystemTimeAsFileTime(&time);
#else
SYSTEMTIME st;
GetSystemTime(&st);
SystemTimeToFileTime(&st, &time);
#endif
FileTimeToAprTime(&aprtime, &time);
return aprtime;
}
and FileTimeToAprTime() is:
/* Number of micro-seconds between the beginning of the Windows epoch
* (Jan. 1, 1601) and the Unix epoch (Jan. 1, 1970)
*/
#define APR_DELTA_EPOCH_IN_USEC APR_TIME_C(11644473600000000);
__inline void FileTimeToAprTime(apr_time_t *result, FILETIME *input)
{
/* Convert FILETIME one 64 bit number so we can work with it. */
*result = input->dwHighDateTime;
*result = (*result) << 32;
*result |= input->dwLowDateTime;
*result /= 10; /* Convert from 100 nano-sec periods to micro-seconds. */
*result -= APR_DELTA_EPOCH_IN_USEC; /* Convert from Windows epoch to Unix
epoch */
return;
}
So, this is what needs to be dealt with to get it working.
