I need to change Zulu time back 1 hour due to the daylight savings time. I have a format I need to follow, which is example P 04:45Z Where the P needs to remain because it signifies proposed, and the Z needs to remain, because it signifies Zulu and the time 04:45 needs to be made 03:45 while preserving the P and the Z, so therefore, P 04:45Z needs to be P 03:45Z . I need this as a formula, because there are a lot of time changes to be made. Can anyone help with this formula?
