The 5.10.0 POSIX module doesn't look like it supplies strptime: 
% perl -v

This is perl, v5.10.0 built for x86_64-linux-gnu-thread-multi
[...]

% perl -MPOSIX=strptime
"strptime" is not exported by the POSIX module
Can't continue after import errors at /usr/lib/perl/5.10/POSIX.pm line
+ 28
BEGIN failed--compilation aborted.

% perl -MPOSIX -le 'print POSIX->VERSION'
