Interesting, but I don't really see why would need to consider them different...
to me it seems pointless, also by the way to represent while day range
must be from
00:00:00 (including) to 00:00:00 (excluding) as with 23:59:59 you miss
milli/nano-seconds.
When I implement date/time related things I always use timestamps in
UTC everywhere
and when need to display to user or pass to some API then convert to respective
format and timezone. Any other way makes it only more complicated.
