I have a code as follows: from django.utils.timezone import get_current_timezone, make_aware make_aware(some_datetime, get_current_timezone()) The make_aware call occasionally raises AmbiguousTimeError: 2013-11-03 01:23:17 I know from the Django docs that this is a daylight savings problem, and that this timestamp is in fact ambiguous. Now how do i resolve it (say to the first of the two possible times this could be)? Zags Prophylactics You should avoid naive datetimes in the first place using the following: from django.utils import timezone now = timezone.now() If like me, you have naive

I know this looks simple. In a Google spreadsheet, I have a column where I enter time in one timezone (GMT) And another column should automatically get time in another time zone(Pacific Time) GMT | PT ----------|------------ 5:00 AM | 9:00 PM As of now I am using =$C$3-time(8,0,0) The problem here is, I want to change the time formula for Daylight savings. Is there any function or script available which can take the daylight saving into calculation automatically. Short answer There is no built-in function but you could build a custom function. Example /** * Converts a datetime string to a

As I know, we can use below to roughly convert a UNIX timestamp to a VB Date CDate([UNIX timestamp]/ 60 / 60 / 24) + "1/1/1970" However, the time zone and daylight information are not considered. Time zone is not a big deal. But I cannot get the daylight bias information for a specific UNIX timestamp. Though, daylight bias of Date 1/1 is obviously different from Date 6/1, however, for Date 3/12 or Date 11/5, the daylight bias calculation is very complex. I tried several APIs, like “FileTimeToLocalFileTime” and “GetTimeZoneInformation” , but none of them work. Here is my code that can not

I need to set up an alarm daily at a given hour. I'm programming the alarm using AlarmManager.RTC_WAKEUP , so it uses the system time as reference. I'm setting the alarm to first execute at the desired hour, then to repeat daily: alarmManager.setRepeating( AlarmManager.RTC_WAKEUP, getTimestampToday("12:00"), AlarmManager.INTERVAL_DAY, pendingIntent ); The getTimestampToday method returns a long timestamp for today at the desired hour. It does so by obtaining the local date for today, then setting the desired hour, finally converting it back to a timestamp (which is UTC based). The problem here

If Cron has a job scheduled to run at 2 am and one at 3 am how would those jobs be affected by daylight savings time? When the time shifts back an hour does the time go from 2:59:59 am to 2:00:00 am directly? Meaning that the 2 am job would run twice and the 3 am job would run once? Or is does the time first change to 3:00:00 am and then 2:00:00 am causing both jobs to run twice? When the time shifts forward an hour does the time go from 1:59:59 am to 3:00:00 am causing the 2 am job to not run and the 3 am job to run once? Or does the time shift from 2:00:00 to 3:00:00 am causing both jobs to
