daytobase's Issues

Implement time module

Currently, daytobase shows record time stamps in UTC. Instead, we have to query and record user's timezone and use it to:

1. Convert UTC time stamps to user's timezone when outputting information
2. Interpret time tags (#t 12:04 pm) and output UTC time stamps

Looks like PyMongo suggests we use pytz module. We need to:

1. Figure out how to serialize/deserialize timezone objects to store them in MongoDB. Let us assume timezone is going to be defined by a string.
2. Write functions that convert from a string representation to pytz timezone object and back
3. Write a function get_datetime_repr(dt, user) where dt is a UTC datetime and user in an object that has a timezone field with a timezone string representation in it, that outputs a string representation of dt in the right timezone.
4. Write a function get_time_tag(message, user) where message is a text of a message, i.e. "ate a banana #t one hour ago", and outputs a datetime object in UTC.

For the latter, use cases we definitely need to handle:

1. "#t 2016.08.23 18:32 flight to London" - we already handle that
2. #t one hour ago
3. #t 12:44

After that is done it would be nice to have at least some minor unittests for these functions.
