To calculate the difference between two time fields in hours, minutes, or seconds, use the following formula:

getTimeDiff({{date_2}}, {{date_1}}, 's')

Where date_2 is the first time point (2nd time field) and date_1 is the second time point. Replace these with your own variables.

You can also change the units of time:

For hours: use ‘h’ instead of ‘s’

For minutes: use ‘m’ instead of ‘s’

For miliseconds: use ‘ms’ instead of ‘s’

Since time fields capture only hours and minutes, this difference is only less than 24 hs.

Note: This formula is valid only for two time fields or time values (same date).

#### Form Builder

In the Form Builder, we added two time fields, three text fields and a button.

#### Rule Builder

In the Rule Builder we added the following rule:

– Condition: When both time fields are present

– Actions: Evaluate our formula and display the result in the respective field

That’s it!
