Right now, I'm working on to change the timestamps(start time & end time) of an old archive. I want to change the time to -7hours (eg:- 12/12/12 11:00 A.M to 12/12/12 04:00 A.M). I know I have to use the piarchss tools with -tfix command but I didn't know on how to specify the -25200 or -7 hour in the time conversion file (-tfix time conversion file). I already refer to PI Server and PI Server Management Guide page 118, but I don't have an idea on how to write it..
May someone teach me on how to write the conversion file of -7 hour ?..I just want to change the hour only, and maintain the minutes and seconds of the archive files.
