Pre-standardized time is a fairly murky place.  For example, 
pre-standardized Japanese time used 12 hours for night-time and 12 hours 
for day-time, with the lengths of each set of hours varying through the 
seasons.  There were adjustable mechanical clocks that worked on this 
system.  I hope no one would argue that this sort of thing belongs in 
the tzdb.
