    javascript calculate elapsed time & update field

    bassicaly i want to dynamicaly update a field on a form based on a calculation between 2 fields.

    the following form is the admin form that the admin uses to edit records.
    my form is as follows:

    Departure Time: 10:00:00 2007-12-12
    (HH:MM:SS YYYY-MM-DD) **Follow Format on left**

    Arrival Time: 12:00:00 2007-12-12
    (HH:MM:SS YYYY-MM-DD) **Follow Format on left**

    Total Minutes: 120
    Total Minutes is from the form on the frontend of the website is submitted, where it is calculated then put into the database

    what i need though is the "Total Minutes" field to update to reflect the changes made to "Arrival Time" or "Departure Time"

    e.g. if i change "Departure Time" to 11:00:00 2007-12-12 then "Total Minutes" changes to 60.

    btw i have minimal knowledge of writing javascript.

    any help would be greatly appreciated
