I have the code in a file and run it with the '-f' option:
gawk -f correct-double-hour.awk test.dat > out.dat
correct-double-hour.awk:
#!/usr/bin/gawk
#
# This script replaces the second instance of 16:00 with 17:00.
BEGIN { FS=","; OFS="," }
$2 != "16.00" { print ; next }
flag == 0 && $2 == "16:00" { print ; flag=1 ; next }
flag == 1 && $2 == "16:00" { $2=="17:00"; print; flag=0 ; next }
Thanks,
