Service Records - The "Since Worked" Field

The "Since Worked" field in a service record is how long since work has been performed on the record. It's the date_worked field expressed as a duration.

When specifying this field in a customized sort or display, any of the names "since_worked", "Last", "Last Worked", "last" (for terse output) or "last worked" (for terse output) can be used.
