Why check strftime result bigger than 2,not 1 not 3?
I have faced different strftime behaviours on two different environments
where unknown specifier was in format string.
On one of them strftime returned 0, this was the expected return value
by me.
But on the other one, strftime returned 2 and put unknown specifier (%s)
as is into the result buffer.
So >2 will handle each cases. In normal behaviour, nowadays, length of
seconds string will be always longer than 2.
Should I put a comment about it into the code?
