Hi,
I came across a bug in gettimeofday() today. Under
some conditions the call can incorrectly return -1
even when it performs the correct operation.
For example, if your timezone is set to "(GMT-10:00)Hawaii"
then the function will return -1.
A patch for this problem is:
*** times.cc.orig Tue Jul 29 23:22:31 1997
--- times.cc Wed Jul 30 15:51:27 1997
***************
*** 103,110 ****
TIME_ZONE_INFORMATION tz;
tzid = GetTimeZoneInformation (&tz);
! if (tzid == TIME_ZONE_ID_UNKNOWN)
ret = -1;
if (p != NULL)
{
--- 103,112 ----
TIME_ZONE_INFORMATION tz;
tzid = GetTimeZoneInformation (&tz);
! if (tzid == 0xffffffff) {
! debug_printf ("gettimeofday: unknown timezone id\n");
ret = -1;
+ }
if (p != NULL)
{
