[Gretl-users] No date information in b-g.gdt example dataset

Hi all, with a fairly recent snapshot I've loaded the shipped example dataset b-g.gdt, which gretl at the bottom announces as 5-day daily and incomplete. OK - does "incomplete" mean gappy here? And there is no information about the starting or ending dates, and possibly not on where the gaps are, either. (Not sure about this one because it's a lot of observations.) Does anybody know more about this data? thanks sven
