Use upper case: POSIX is a Core module installed with Perl. 
perl -MPOSIX -E 'say POSIX::strftime("%m%d%H%M",localtime(time()))'

Re^4: Epoch to specific output

    I am using Perl v5.8.4 on an Intel based machine with Solaris 10 64bit operating system.

    The capitalized POSIX was accepted but I am receiving other errors now.

    Input:
    perl -MPOSIX -E 'say POSIX::strftime("%m%d%H%M", localtime(1388679108))'

    Output:
    Unrecognized switch: -E (-h will show valid options).

    Input:
    perl -MPOSIX -e 'say POSIX::strftime("%m%d%H%M", localtime(1388679108))'

    Output:
    Bareword found where operator expected at -e line 1, near "say POSIX::strftime"
    (Do you need to prodeclare say?)
    Execution of -e aborted due to compilation errors.

      Your version of Perl is too old. -E requires perl 5.10. Use -e and print instead. 
      perl -MPOSIX -e 'print POSIX::strftime("%m%d%H%M",localtime(time())),$
