Ah, yes.  I had forgotten about that.  In fact, my experience while
roaming in Hong Kong was even worse: the timestamp is in the local time
of the _sender_, not the SMSC.  Messages I got from people in Hong Kong
were marked in Hong Kong time, and messages I got from people back in
Finland were marked in Finnish time, with no indication of timezone.
(In fact, I suspect that the timestamp is generated on the mobile phone,
using whatever time its user has set.  Worth an experiment?)

We probably need a better definition of what the timestamp field 
actually means for Kannel.  Some SMSC drivers fill in the time of
receipt, others take the time from the message, and not all do this
in GMT.  So I think the first question is, what do people use the
timestamp field for?  If there are multiple conflicting uses,
then maybe we need multiple timestamp fields -- time of receipt
separate from sending time, and timezone marked separately if known.
