Error when displaying Timeline on Trac 1.2

[sdegrande]

When opening the Timeline (Trac 1.2, python 2.7), I get this error:

Traceback (most recent call last):
  File "/usr/local/lib/python2.7/dist-packages/Trac-1.2.dev0-py2.7.egg/trac/timeline/web_ui.py", line 202, in process_request
    events.append(self._event_data(provider, event))
  File "/usr/local/lib/python2.7/dist-packages/Trac-1.2.dev0-py2.7.egg/trac/timeline/web_ui.py", line 380, in _event_data
    dateuid = to_utimestamp(date)
  File "/usr/local/lib/python2.7/dist-packages/Trac-1.2.dev0-py2.7.egg/trac/util/datefmt.py", line 112, in to_utimestamp
    diff = dt - _epoc
TypeError: unsupported operand type(s) for -: 'int' and 'datetime.datetime'

Attached is a patch to fix the issue.

Thanks for you work.

Thanks for the patch. The change is needed due to the removal of deprecated parts of the API in ​[trac 13589].

In 14881:

0.3dev: Returning a datetime object is enforced in Trac 1.1.3 and later.

Patch by sdegrande. Fixes #12482.

In 14882:

0.3dev: Don't rely on transitive imports. Refs #12482.

from tracdownloads.api import * brings in to_datetime and utc.
