The type requires it though. No, comparison doesn't require the time zone, but
many (most?) of the other operations do. And the type can't be separated from
the time zone. That's part of the whole point of how SysTime is designed. It
holds its time internally in UTC and then uses the time zone to adjust the
time whenever a property or other function is used which requires the time in
that time zone. That way, you avoid all of the issues and bugs that result
from converting the time. The cost of that is that you can't not have a time
zone and use SysTime. So, if someone cares about saving that little bit of
extra size in their executable by not using the time zone, they're going to
have to use the C functions or design their own time code.
The time zone info can be lazily initialized only by those operations that need
a time zone.
