class SchedulerPlugin(IPlugin):
"""Plugin to support scheduling messages to be parsed at a later date.
Special tags #weekly, #daily, #hourly are do what they should do, although the behaviour of messages which give these tags with a datum time is undefined.
These frequency tags can be combined, though I am not sure of the utility (or even bug-free-ness) of this in its current implementation.
The interplay between timezones:
* server in one TZ and user in another,
* "remind at 10pm"
is also not thoroughly tested, and not expected to work.
