Re: A module to add methods to convert datetime between UTC and user's timezone

Thanks Graeme and Dominique.  What I'm looking for is a collection of methods that are not covered in Date and Datetime classes of vanilla Odoo.  For example:
    # Convert datetime object to date string
    def _convert_to_user_date_string(self, datetime, hours):
        user_datetime = datetime + relativedelta(hours=hours)
        return fields.Date.to_string(fields.Date.to_date(user_datetime))

    # Convert date string with timestamp to datetime object
    def _convert_to_user_datetime_string(self, date, timestamp, hours):
        datetime_value = fields.Datetime.from_string("{} {}".format(date, timestamp))
        return fields.Datetime.to_string(datetime_value - relativedelta(hours=hours))

    # Return the time difference (in hours), e.g. if user's timezone is in
    # GMT+9 this method will return 9.0
    def _get_tz_hours_diff(self):
        tz = timezone(self.env.user.tz or "UTC")
        current_time = fields.Datetime.now()
        user_time = pytz.utc.localize(current_time).astimezone(tz)
        utc_time = timezone("UTC").localize(current_time)
        hours_diff = (
            (user_time.utcoffset() - utc_time.utcoffset()) / timedelta(minutes=1) / 60
        )
        return hours_diff

I vaguely remember seeing somewhere someone extending Date and Datetime in a somewhat similar manner.  If there is nothing under OCA we may create a module and make a PR.

It is built in to odoo and sometimes uses babel under hood.

For today jobs fields.Date.context_today(record with tz context, optional timestamp) is my general go to available in views as context_today.

odoo.tools.format_datetime or something like that does it too for datetime plus locale specific representation as string.

There is some more. Check fields.Date* and odoo.tools 

In record rules it is tons harder but if you have the patience you can handroll a very ugly rule using time module.

i would be curious if there is one, or contribute for developing one

UTC --> user timezone is a real real pain to develop. particularly when trying to get "today" jobs

I think I've seen somewhere under OCA a module to add generic methods to convert datetime between UTC and user's timezone, but I somehow can't find it now.  A pointer would be appreciated.
