Daylight saving goes into effect at 3:00am instead of 2:00am. Below I have attached simple test case. This is the output of the test I ran on both Mac(10.2.8) and PalmSim bash-2.05a$ TZ="Europe/Paris" ./a.out when = 0x3f9b0e44 is_dst = 1 zone = CEST Sun Oct 26 01:59:00 2003 when = 0x3f9b0e80 is_dst = 1 zone = CEST Sun Oct 26 02:00:00 2003 when = 0x3f9b11c8 is_dst = 1 zone = CEST Sun Oct 26 02:14:00 2003 when = 0x3f9b2014 is_dst = 0 zone = CET Sun Oct 26 02:15:00 2003 You will notice that the difference between 02:14:00 and 02:15:00 is 3660 which is 61 minutes. If you set the device to 2:14 and wait 46 minutes it will change the time back to 02:00. There should be no difference in setting the time to 02:00, 02:14, or 02:15 since anytime after 02:00 should fall outside of Daylight Saving Time on this date. Thanks, --jason
