pytz

I am working on a Django web based project in which i need to build a application which work in the following sequence: 1) user open a page in which he need to enter a command and a time 2) Django application will execute that command at a given time on each day till user off the scheduler (by default it is True) What i am facing the problem is that : 1) How should i execute the commands on a time but on each day. To save the commands and time i created a following model in my models.py class commands(models.Model): username = models.ForeignKey(User) command = models.CharField(max_length=30)

Let's say I receive an arbitrary datetime object in a request, like this, which could be coming from any possible timezone - I don't know which one. For the sake of example, pretend it comes from the East Coast import pytz from colander import iso8601 ... ests1 = iso8601.parse_date('2016-04-01T00:00:00.0000-04:00') pretend ests1 is the object that comes in Using pytz, I can find out a bit about it's timezone etz = ests1.timetz() # 00:00:00-04:00 etzi = ests1.tzinfo # <FixedOffset '-04:00' datetime.timedelta(-1, 72000)> etzn = ests1.tzname() # '-04:00' # EST edst = ests1.dst() # '0:00:00' Note

This question already has an answer here : Closed 6 years ago . Possible Duplicate: Weird timezone issue with pytz This seems wrong: >>> import pytz >>> z1 = timezone('America/Edmonton') >>> z2 = timezone('US/Mountain') >>> z1 <DstTzInfo 'America/Edmonton' LMT-1 day, 16:26:00 STD> >>> z2 <DstTzInfo 'US/Mountain' MST-1 day, 17:00:00 STD> >>> pytz.VERSION '2012f' >>> 'America/Edmonton' and 'US/Eastern' should be the same time zone (17:00:00 STD). Not to mention 16:26:00 doesn't make any sense. -- Update -- The above makes sense in context of Jon Skeet's answer. However, things get strange when I

I have a requirement to convert a date from a local time stamp to UTC then back to the local time stamp. Strangely, when converting back to the local from UTC python decides it is PDT instead of the original PST so the post converted date has gained an hour. Can someone explain to me what is going on or what I am doing wrong? from datetime import datetime from pytz import timezone import pytz DATE_FORMAT = '%Y-%m-%d %H:%M:%S %Z%z' def print_formatted(dt): formatted_date = dt.strftime(DATE_FORMAT) print "%s :: %s" % (dt.tzinfo, formatted_date) #convert the strings to date/time date = datetime

I have a naive date and time in the format '2012-05-19 19:13:00' and need to store it using Django 1.4 and its timezone-aware abilities. Although there is no way of knowing what timezone the date is originally in, it seems to make sense to store it as if it were UTC. However, using pytz etc, I'm not sure how to convert a date that has no timezone into a UTC datetime. If it has no tzinfo then of course there can be no conversion to UTC. Instead you could just make the datetime object into an time-zone aware one: import datetime from pytz import UTC dt = datetime.datetime.now() # just some date
