I specically avoided giving a way to get the time with any type other than
SysTime (and TickDuration for using a monotonic clock), because I believe that
it leads to incorrect behavior. Any time that you're dealing with the system
clock, you should be dealing with SysTime. Date, TimeOfDay, and DateTime are
for when you need the date and/or time but don't care about what absolute time
it's associated with in the real world. Treating DateTime as corresponding to
a specific point in time is just going to cause problems, because it has no
time zone. It could correspond to over 24 different times. By restricting
getting the time to SysTime, it encourages the writing of correct code.
