[WriteLog] Anyway to easily subtract 1 hour from logged contacts.

[dr]

I just happened to notice that all my SS CW contacts are 1 hour ahead of the
actual UTC time.

Is there an easy way to subtract 1 hour from each contact in a log after the
fact?

My Writelog DXCC log has probably been off an hour for a long time and I
just have not been paying close attention.

Thanks
