timezone

问题 I am using git-bash on a Windows system. The Windows clock shows local time, but inside git-bash everything is in GMT time: $ date Mon Mar 31 16:08:57 GMT 2014 Also setting TZ will not change things: $ TZ="Europe/Berlin" date Mon Mar 31 16:09:01 GMT 2014 Similarly all times it git log are GMT only. Is there a way to set the correct timezone in git-bash? 回答1: On Windows the TZ variable seems to work differently. To get the German timezone you have to write: TZ=GST-1GDT date If you set it to

问题 Is there a built-in library or does anyone have available a function to convert a string timezone such as "America/New_York" to a datetime.tzinfo object? Thanks. 回答1: Yes, you need the pytz library: import datetime, pytz zoneName = 'America/New_York' now = datetime.datetime.now(pytz.timezone(zoneName)) returns: datetime.datetime(2011, 3, 16, 1, 39, 33, 87375, tzinfo=<DstTzInfo 'America/New_York' EDT-1 day, 20:00:00 DST>) 来源： https://stackoverflow.com/questions/5321466/how-to-convert-string

问题 This question already has answers here : How to detect the timezone of a client? (4 answers) Closed last year .

Is this method wrong? Is

问题 I am doing an IP lookup to determine a "best guess" for timezone offset from UTC and the country/region information. So, for instance, I have offset -3 and country Brazil. I want to show BRT instead of a random timezone in that same offset, i.e. ART Is there some built-in way in PHP to be able to set the appropriate timezone with this information? If not, what would be the easiest way to do this? (Assume that I can't make any outside API calls) If I do my own database table, how do I ensure

问题 In Django documentation for setting timezone, the list of available choices for timezone are actually postgres timezone parameter strings. So it seems Django uses Postgres for retrieving time. If so, then the problem is that IST is used to denote both Indian & Israel Standard Time, but postgres uses IST for Israel Standard Time (potentially confusing over a 6th of world's population) and there is NO timezone string for Indian Standard Time. Not just that, Postgres also misses timezone for

Use shell command on server: mysql

问题 I have a data set with the following information: latitude, longitude, EST time.

Any suggestions of how to do this with R? Thanks! 回答1: lat = 13 long = -2 time1 <- as.POSIXct("2014-02-12 17:00:00", tz = "EST") # https://developers.google.com/maps/documentation/timezone/ apiurl <- sprintf("https://maps.googleapis.com/maps/api

问题 I have a Java app that needs to be cognizant of the time zone. When I take a Unix epoch time and try to convert it into a timestamp to use for an Oracle SQL call, it is getting the correct timezone, but the timezone "useDaylightTime" value is not correct, i.e., it is currently returning "true", when we are NOT in DST (I am in Florida in TZ "America/New_York"). This is running on Red Hat Linux Enterprise 6, and as far as I can tell, it is correctly set up for the timezone, e.g. 'date' returns:
