189

Fixed #189 . This error was due double parsing of time field, one during form rendering and another in template filter.

Time should always be stored in UTC. From this patch it appears time is not being stored in UTC.

Somewhere we went wrong, I think we should create new column for datetime timezone field to store timezone and convert the datetime to UTC. While displaying convert UTC to respective timezone. Alembic migration need to address existing data. Does that sound right ?

Dates should always be stored in UTC. We used to do that earlier. Can you
look at current data in db?

I looked into DB.

jsFoo 2012 hacknight start time is 12.00PM (http://hacknight.in/jsfoo/2012#/participants).

DB Value 2012-10-13 06:30:00, IST is + 5.30 UTC. While editing the form start datetime is 2012-10-13 6:30am.

Same for other events.

What user enters is not what user sees. Looking into the commits of coaster and Hacknight

So the form edit isn't setting timezone. You have to set form.start_datetime.timezone = app.config['TIMEZONE'] in the view (similarly for end_datetime).

Yes, /edit endpoint needs a fix. /new also faces same issue. This is because https://github.com/hasgeek/baseframe/blob/master/baseframe/forms.py#L188 fails. Assigning timezone value to form doesn't work. One way to solve the issue is to have validate_start_datetime.

[kracekumar]

Now datetime is displayed properly.

This is can't be right. If the date is stored in UTC, you need to convert to the correct timezone when displaying or it will display in UTC.

Yes, something is still wrong, converting to tz puts back same behaviour.
