timezone

问题 I do let fullcalendar initialize normally. So it represents current date. (Midnight->midnight, 1day, 1h slots) From some other datasource I get data with timestamps. The format is "YYYY-MM-DD HH:mm" (transmitted as a string, no timezone information) So I convert that string to a moment object and test against fullcalendar.start and .end to see if it is within. moment("2016-04-07 00:00") == $('#calendar').fullCalendar('getView').end This results in false though the following command $('

问题 I am using dataframe.index = dataframe.index.tz_localize('Iran') to localize my Pandas dataframe datetime index. The problem is Django rises a NonExistentTimeError .

问题 I'm struggling to understand how "AT TIME ZONE 'localtime'" exactly work? By playing with it, I found out that it acts exactly as "AT TIME ZONE 'UTC'" ... But why? Is "localtime" a synonym of "UTC" in postgres? Or it comes from some setting (environment? connection timezone? although checked both, seems they are not related)... There's "localtime" function but I think it is not involved here. Sample SQLs: # date Thu Dec 8 12:00:05 AEDT 2016 # SELECT LOCALTIMESTAMP; ---------------------------
