Help on Date Format

[Arante, Susan]

Could someone tell me why this is happening?  When I use this command, it
used to give me 20010405.doc (yyyymmdd.doc), now it's giving me 2001 4 5.doc
- I'm losing the leading zeros.  
Command is on Perl 5 - printf("\%s%02s%02s.doc",$year,$month,$day).

Thanks.
