You're welcome; and support for high frequency data would be a
nice thing to have in gretl.

Yes, specifying the periods in the data file is the tricky part!
I would be quite surprised if their seasonal adjustment routines
work for hourly data, but that is said out of gross ignorance on
my part. I can't find an X-12-ARIMA mailing list on which to ask
questions -- it seems there's only an "announce" list -- so I
guess the only option is to search the manual.
