Hey all,

I have a shell that invokes a AWK.
In this AWK i want invoke a function that receives 3 parameters:

  1. date: 20080831
  2. time: 235901
  3. duration: 00023

that function receive this 3 parameters and sum to this value two more seconds:

2008083123590100025

Remember that in case that I have 23h 59m and 59s, the additional 2 seconds should change the time to the next day...

The output of the function is this value... that i need to get him in my AWK...

How can I do this...??? can anyone help me?

thanks

The regular advice would be to convert to canonical time and then back. See the FAQ for more.
