updated property
Updated is when anything in this room's work last moved, in unix seconds. ABSENT when the room has no work at all: zero would read as the epoch, and a room nobody has filed anything in has no last activity rather than an infinitely old one. Total is 0 in exactly that case.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
