im using Date::Manip to convert dates and times eg 2007:08:02 12:23
to allow me to sort them,
Why are you doing that?
C:\home>type test.pl
@dates = ( '2007:08:02 12:23', '2007:10:21 04:40',
'2007:06:05 16:08', '2007:09:11 22:20', );
print "$_\n" for sort @dates;
C:\home>test.pl
2007:06:05 16:08
2007:08:02 12:23
2007:09:11 22:20
2007:10:21 04:40
im sorting it on a key of the hash
my @daylistsorted = sort { $$a{'START_DS'} <=> $$b{'START_DS'} }
@daylist;
generates a
Argument "2007:09:30 13:41" isn't numeric in numeric comparison (<=>)
at ./518573
My point is that the format "yyyy:mm:dd hh:mm" is sortable without
conversion. However, you need to sort lexically, i.e. use the cmp
operator instead of the <=> operator.
