handling elapsed time data
I am trying to import and run calculations on data dealing with total time
logged into a phone system for a group of users. the data is in the following format: User Date Total Time user1 1/1/10 7:45:32 user1 1/2/10 6:31:45 user2 1/1/10 8:05:45 I have found many suggestions for how to calculate elapesd time, but cannot seem to find how to store/format data already in this format. I am needing to store the data this way in the table so I can run totals for users/date ranges. Any suggestions? |

handling elapsed time data
Brad -
If you can work with decimal hours, that might be one way to store your values. That would be a numeric field, and is 24 times the value calculated as the time difference. So the Total Time of 7:45:32 would be 7.75889 hours (just over 7 3/4 hours); 6:31:45 would be 6.52917 hours (just over 6 1/2 hours), etc. Being a numeric field, you can add and subtract hours easily. You might get a weekly value of 41.365 hours for a user, which would be OK. To set this up, just add another column to your table that is numeric (single or double). Run an update query that takes your 'Total Time' column and multiplies it by 24 and places the result in the new decimal hours column. Depending on your needs, you can remove the total time column once your code is set up to regularly populate the decimal hours column. Hope that helps! -- Daryl S "brad" wrote: I am trying to import and run calculations on data dealing with total time logged into a phone system for a group of users. the data is in the following format: User Date Total Time user1 1/1/10 7:45:32 user1 1/2/10 6:31:45 user2 1/1/10 8:05:45 I have found many suggestions for how to calculate elapesd time, but cannot seem to find how to store/format data already in this format.

Thank you! I will try this as well. There is a large amount of data so this
may be easier to work with. Thanks. "Daryl S" wrote: Brad - If you can work with decimal hours, that might be one way to store your values.
