Well, all in all, it's an example of why std.datetime.SysTime holds its time 
in UTC and does all comparisons with that value with no regards to time zone 
such that it's only when presenting its value does it convert it to the 
appopriate time zone (e.g. when converting to a string). DST tends to screw up 
all kinds of stuff for programs dealing with time.
