I'm trying to create AWK script that will filter the input file according to some pattern, and use the strftime() function for some calculations.

($2 ~ /^[HB]/ && $2 ~ /n$/){
        print strftime("%Y")
}

The interpreter in use is mawk. When triggering this script using this command:

awk -f script3 inputFile

I'm getting the error: "function strftime never defined"

awk strftime
