It's pretty clear if you're a time nerd like me. :-) The standard for 
strftime says "The appropriate characters are determined using the 
LC_TIME category of the current locale and by the values of zero or more 
members of the broken-down time structure pointed to by timeptr, as 
specified in brackets in the description. If any of the specified values 
are outside the normal range, the characters stored are unspecified."

The "zero" means that if no conversion specs are present in the format 
string, then no struct tm members are examined, and it's therefore OK 
for all members to be uninitialized if no conversion specs are present.
