Re: Query........Manipulating TimeFields

John,

I've done something similar to what your trying for using query.

 

If time1 & time2 are numeric fields, then:

    - use DIGITS to change time1 to a character field

    - use the substring function to strip out the hours, minutes and seconds from the character field

    - use the concatenate function to "build" a new char field, using the hours, minutes and seconds,

      with a format of HH:MM:SS

    - use the TIME function to create a new field, that will be a numeric representation of a time field

  

If you do this for both fields, you can then subtract the resulting time fields.  The result will be something like

304.  This is actually 3 minutes, and 4 seconds.  If you want to calculate the average response time, then

follow the steps outline above (again), this time using the difference between the time fields.

(In other words, you'll start with 304, and end up with a numeric representation of a time field.)

You can then use the SEC, MINUTE and HOUR functions to extract those portions of the time field. 

Then, you can average the individual SEC, MINUTE and HOUR fields.

 

That should be as clear as mud! LOL!

 

If you have any question, feel free to contact me.

 

HTH,

 

Dave

Subject: Query........Manipulating TimeFields

Could someone please point me to some reference material on how to work with fields containing time stored as a numeric (len6, dec 0.)  Specifically, I need to calculate elapsed time between twor or more time fields.  Seems to me I need to create a Result Field but am not certain of the correct formula to to the calculations between time1 and time 2 to get Elapsed_Time.
