I have
import arrow s = '2015/12/1 19:00:00' tz = 'Asia/Hong_Kong' How can I parse this with Arrow such that I get an Arrow object with the time zone tz? The following defaults to UTC time.
In [30]: arrow.get(s, 'YYYY/M/D HH:mm:ss') Out[30]: <Arrow [2015-12-01T19:00:00+00:00]> I know the .to function but that converts a time zone and but doesn't allow me to change to time zone.
Try this:
arrow.get(s, 'YYYY/M/D HH:mm:ss', tzinfo=tz) If you are also using dateutil, this works as well:
arrow.get(s, 'YYYY/M/D HH:mm:ss', tzinfo=dateutil.tz.gettz(tz)) So does this:
arrow.get(s, 'YYYY/M/D HH:mm:ss').replace(tzinfo=dateutil.tz.gettz(tz)) 
In [7]: arrow.get(s, 'YYYY/M/D HH:mm:ss').replace(tzinfo=pytz.timezone(tz)) Out[7]: <Arrow [2015-12-01T19:00:00+07:37]>
arrow still fails to convert utc datetime to a named timezone, convert utc time to local timezone, and round-trip timestamp -> named timezone -> utcpytz but it might too low-level for most applications. Though all you need is to understand why pytz introduces localize(), normalize() methods, to use it correctly.I'm not qualified yet to add a comment and would just like to share a bit simpler version of the answer with timezone str expression.
s = '2015/12/1 19:00:00' tz = 'Asia/Hong_Kong' arrow.get(s, 'YYYY/M/D HH:mm:ss').replace(tzinfo=tz) or simply local timezone:
arrow.get(s, 'YYYY/M/D HH:mm:ss').replace(tzinfo='local') or specified ISO-8601 style:
arrow.get(s, 'YYYY/M/D HH:mm:ss').replace(tzinfo='+08:00') 
arrow.get uses UTC as default, and not the local timezone.Per the current documentation, you can also provide a default timezone for arrow.get(), e.g.:
s = '2015/12/1 19:00:00' tz = 'Asia/Hong_Kong' arrow.get(s, tzinfo=tz) However, as of right now (version 0.12.1) there is a shortcoming where that doesn't work for string-based date parsing. Fortunately, this has been fixed, so the next release of Arrow will integrate this fix.
This is working for me as of 0.10.0:
import arrow s = '2015/12/1 19:00:00' tz = 'Asia/Hong_Kong' arrow.get(s, 'YYYY/M/D HH:mm:ss', tzinfo=tz) # <Arrow [2015-12-01T19:00:00+08:00]> However, arrow.get('2018-01-29 14:46', tzinfo='US/Central') (i.e. without the format string) ignores the tzinfo parameter.
