It also depends on the TSEL and TSE fields, which can cause the timestamp to 
be fetched from another record (if you point TSEL to another record's .TIME 
field), an event system (set TSE or point TSEL to a numeric field giving the 
event number) or assume that device support has set the timestamp itself (set 
TSE to -2).
