Title:
  Needing standard/good functions for date/time output in user's
  timezone for account reports

Status in OpenERP Server:
  Confirmed

Bug description:
  I've run into a problem of not having correct timezones applied when
  generating reports. This is partly the fault of the server's timezone
  being forced to UTC, but also due to the lack of availability of easy-
  to-use functions in the templates used to generate these reports.

  What I have done as a proof of concept is to add "import pytz" into
  openobject-server/openerp/report/report_sxw.py, then add pytz and
  datetime into the localcontext member variable in rmlparse.

  This change allows me to call pytz and datetime from within the report
  templates (most specifically I've been looking at the internal
  header/footer templates for companies). I find this to be preferable
  over formatLang and time.strftime calls, which do not really allow for
  timezone changes. formatLang is something of an exception here - it is
  meant to take a date or datetime string of a particular format and
  correct the timezone for it, however this breaks easily, and seems
  superfluous.

  What I use currently for correct date and time in the templates are:
  Date: [[ datetime.now(python.timezone(tz)).strftime('%Y-%m-%d') ]]
  Time: [[ datetime.now(python.timezone(tz)).strftime('%H:%M') ]]

  What I think would be much better is easy access to standard objects/functions that will output dates, times and datetimes in the user's timezone. So that we might call them with something like:
  Date: [[ utime.today() ]]
  Time: [[ utime.localtime() ]]
  Datetime: [[ utime.now() ]]

  I would also like the flexibility to provide my own strftime string.
  I have no attachment to these names for functions/namespaces/objects.
