[Trlog] Log Correction

[Gene Fuller]

Could anyone give me the "how to"  to make a bulk correction to the dates shown on my contest log. i.e. I started the contest on Friday the 3rd instead of the 2nd, so I need to increment -1 for all the dates. I know it's a fairly easy fix because I figured it out once before a few years. Figuring that I would never do anything that dump again I didn't leave myself any notes. I probably could figure it  out again but thought someone might be kind enough to save me some grief. - and I'll leave myself some notes this time - thereby assuring myself that I'll never make the mistake again 

Thanks and 73's,

Gene / W2LU
