also, even if one's computer always stays in the same place, 
Daylight Savings can change the timezone you're in, while 
grub.cfg stays the same.

What is it that we're doing when we "ignore" it 
specifically? Assuming local-time and hardware-clock-time 
are both UTC? (and therefore if the date specifies a 
timezone, which is specified numerically, convert the time 
to UTC before doing anything with it)
(The above behavior means that if the hardware-clock is 
actually local time, one could specify the time without a 
timezone / with timezone Z, and it will work to set the 
time, despite the incorrect assumptions.)
