Here are a couple notes on Duration fields:

Here's how you can calculate a duration. By default, durations are stored in miliseconds. By using the same syntax, you can perform about any type of calculation.

Note that the example is using the actual "duration" field, as well as the "dateNumericValue()" function.

In general, times needed to be converted to an integer in order to do calculations, and then maked as a glide_duration type field in order to be shown as a human-readable format.

Essentially, you're just setting a field attribute to "format=glide_duration" for display.

Hi, I want to reset a duration field to 0 and tried the above mentioned two ways but nothing seems to work.
First I tried :-
g_form.setDisplayValue('calendar_duration', '0 00:00:00');

Also tried to follow the instructions on the link:-
http://wiki.service-now.com/index.php?title=Duration_field_addition

Any suggestions on resetting the duration to 0 will be appreciated.
Thanks,
Shilpi.

Are you trying to set the field via a Client Script, or a Business Rule? The syntax is different for both.
