As long we stay invariant with system time, time zone etc.. LocalDates 
should be
fine.

Archives can potentially be long lived, however, so caching a range of 
LocalDates
that is centered around the system time when creating the archive might 
lead to
degrading startup over time. Not sure that's a pleasant property to have.
