Thank you for your response, unfortunately for this field, i'm allowing the user to input the time as well as being able to use the 'Now' button.
For my scenario, I need the 'Now' button to populate the field with the UTC time so that the user can see the time in UTC.
I cannot use the valueChange event to change the time when the now button is clicked because I don't know if the event is triggered by the user updating the field manually or if the field is populated by the 'Now' button. If the valueChange event is from the user manually entering the time, I don't want to make any changes to the value, but if the event is fired by clicking the 'Now' button, I want to change the value to UTC.
Is there a way for me to intercept the 'Now' button event in order for me to do further processing before displaying the time in the field?
