SysTime.init.toString unconditionally dereferences the timezone field
(indirectly - it calls adjTime which does so), which will be null for
SysTime.init.

This needlessly complicates debugging - writeln(t) will segfault if t has not
been set.

Question: what should be returned? null? "null" the string literal (like what
printf does for null pointers)? The time sans timezone ("0001-Jan-01
00:00:00")?
