I would like some sugestions on how to solve the following problem with removing selected data from fields. Each day I receive a file containing 22,000 records that I use a combination of awk and the cut command to remove unwanted fields. This is a work in process as I learn more about awk, sed and other tools.

The problem I am struggling with is how can i remove only the time stamp, days, day from the last field? I only want the number days in the last field. For days less than 1 if I can place a "0" in field great, I think a blank will work for now.

Below is a sample of the file output.
Thanks
