| hopIdOrName | The hours of operation schedule name (for example, 24x7 or 9 to 5) that determines the working and non-working schedule. See [Setting Up Hours of Operation](docId:_Qp9OyhXNF2bF5FnN2NEX). |
| utcStart    | The start date and time to be compared.                                                                                                                                                    |

## Returns Value

Number value.

If the value of the** startDateTime** parameter is earlier than the value of the** endDateTime** parameter, the returned value is positive. If the value of the** startDateTime** parameter is later than the value of the **endDateTime** parameter, the returned value is negative.

## Example

`$(DiffWorkingSeconds("24 x 7", "4/5/2015 11:36 AM", "4/6/2015 11:36 AM"))`

returns the number of seconds in a working day, which in this case is 28,800 seconds (8 hours x 60 minutes x 60 seconds), assuming that there are no exceptions during that time defined in the HOP schedule.
