Bibsched running tasks at fixed time

I have updated the get_runtime function to be able to run oaiharvest at 4:00 sharp.

Hi Alessio,

this ticket is kind of implementing the request in ticket #896, that was closed as duplicate of #794. However it's true that this is implementing a different concept, namely to have no time drift at all.

I have to comments on your patch:

• is it Python 2.4 friendly (in particular WRT the different time Vs. date strptime functions)?
• in your implementation, when the var argument to get_datetime is not matched by the regular expression (and contains therefore a regular date), you completely ignore it:

-        date = time.strptime(var, format_string)
-        date = time.strftime(format_string, date)
+        date = date.strftime(format_string)

while before it was used to build the date value. In this way you are changing the semantic of get_datetime even when you are not specifying the new now argument.

It works fine with python2.4.

I may have taken a shortcut in my understanding and I just assumed it was a fallback in case the timeshift was invalid.
There is really not point in changing the else branch and we can just keep the old one.

BibSched: handles task to be run at fixed times

- introduce new --fixed-time CLI argument for bibtasks that allows
  admins to require that recurrent tasks are re-scheduled using
  exact multiple of the sleeping-time with respect to the current time.
