That's not needed in the simple devices that I help maintain.  They log UTC.

If devices need to put local time into a log for some reason, then they can log 
the UTC offset.  That is simpler and more reliable than logging the tz version 
number would be.

The problem of managing historical data is one that primarily concerns 
operations and system maintenance.  It's not something that low-level devices 
should need to worry about.  So it should be OK to make any version-control 
features optional.
