Any EXCEL gurus out there?

[RAP]

Have imput the entire WC schedule from online site into my EXCEL file (found many errors). Header columns are: DATE/TIME/M/F/EVENT/ROUND. All times are BERLIN times. Is there a shortcut way I can subtract 7 hours to make the times Central time? Don't want to go row by row and change the times. Can this be done in EXCEL using some type of sum function? Any help would be appreciated.

Dates and times can be added and subtracted in Excel but there are a few tricks. Simple reference here.

If you are running Vista, you can also have multiple time clocks on display. Reference

Insert two new columns next to the column of times. In the first new column, fill it with 7:00. In the second new column use the function =A1-B1, etc., as follows:

22:30 7:00 15:30 (=A1-B1)
20:00 7:00 13:00 (=A2-B2)
19:30 7:00 12:30 (=A3-B3)

This should work. You can then convert the third column, using Copy, Paste Special, Values. Then you can delete the first and second column, and you'll be left with a column of Central Times.

All of our Olympic database started out in Excel so I've used it quite a bit over the years.

Thanks bambam. I got what I wanted. Not familiar with the PASTE SPECIAL deal so that is what probably messed me up. After I CUT/PASTED the new values into column B and deleted the "700" column, column B then changed to "#....!" forget the word that came after the pound sign. Did not know how to handle this so I just hid the column that contained "700". It's probably in the PAST SPECIAL step that I went wrong. Anyway, this is my finished product. Thanks again. Hmmm, in the preview of this msg, my columns got squeezed together. Oh well.
