Change time zone offset

I want to change the offset in column D of the Sheet1 tab to the format shown in column G of the TZ tab.  I want to be able to enter + or - values.

It will be less confusing to read and easier to enter that way.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Hello rtod2,

Under Tools menu there is a data validation option. You can set up a list based on a cell range or just list the values within data validation, I did the latter and listed all values from 12 to -12 in increments of 0.5, you can change that as required. I did that for D5 and then copied down, see revised sheet

regards, barry

Looks like it messed up the output?

No, I don't think so. I just changed some of the entries to demonstrate the range of values that can be picked. I just changed them again to 1s and zeroes but you can obviously pick anything from the list.

regards, barry
