I think there are the following issues with rB5fa6cdb77a98: Add unit for time stored in seconds:
- it does not take preferred unit settings into account
- if we introduce a PROP_UNIT_TIME_ABSOLUTE unit, shouldnt it be visible
to RNA as well?
- seems like a double entry sneaked into that commit?
This is in preparation to use this for render time limit in cycles-x (if
a user decides to input this as minutes [or even hours]).
