You may consider the substr function:
substr($1,1,2)":"substr($1,3,2)

Hope This Helps, PH.

Hi

[gray]# any awk[/gray]

[blue]master #[/blue] echo '0023' | awk '{$1=substr($1,1,2)":"substr($1,3)}1'
00:23

[gray]# GNU awk[/gray]

[blue]master #[/blue] echo '0023' | awk '{$1=gensub(/(..)/,"\\1:","",$1)}1'
00:23
