Hi there,
I'm feeling some pain while wrangling with timezones in an office room
booking application. I'm storing bookings in a MySQL database and want to
display them in the timezone local to the office room, so it is not
necessarily local to the user's local machine timezone.
Here is my model's datetime definition:
class Booking(models.Model):
date_time = models.DateTimeField()
When the booking is stored, it comes back from a post and I store it in the
DB as such:
dt = datetime.datetime.strptime(request.POST["date"] + " " + request.POST[
"time"], "%Y-%m-%d %H:%M")
dt = pytz.timezone("America/Toronto").localize(dt)
Printing the value of dt after that call, it looks correct.
Later on, I pull that booking out of my database by ID and render it in my
template, rendering the datetime like this:
<small>{{booking.date_time}}</small>
I've tried re-interpreting the timezone after pulling it out of the
database, to no avail. When I print the datetime object directly after it
is pulled out of MySQL, I get it in UTC like so:
2014-08-30 16:00:00+00:00
Re-interpreting it to force it into the office's local timezone, I get the
correct result but 1 hour off is still rendered in the web browser
# returns 2014-08-30 12:00:00-04:00
booking.date_time = pytz.timezone("America/Toronto").normalize(booking.
date_time)
The result of this is the time is rendered *1 hour behind* the actual time.
This is consistent across all datetimes I've tried, and I seem to be
unable to get Django to render the correct time.
My question is this: Why is my datetime consistently rendering 1 hour off,
and how do I wrangle it into rendering at the true time?
