Captures the time it took to assign a task

[chetnadev]

This Business Rule in ServiceNow is used to track how long it takes to assign a record after it is created, typically on a task table like Incident, Change, or a custom table.

If this is the first time the record is being assigned (i.e., u_assigned_time is empty):
Sets the field u_assigned_time to the current time.
Calculates how many minutes passed since the record was created (sys_created_on).
Stores that difference in a custom field u_time_to_assign (as a string like "15.33 minutes").
If the record was already assigned before (u_assigned_time is not empty), it just logs that and does nothing.

While this is possible to do via Metrics in ServiceNow (https://www.servicenow.com/docs/bundle/xanadu-platform-administration/page/use/reporting/concept/c_SampleFieldValueDurationScript.html), the script is being provided to potentially solve some edge cases.
