Have just been reminded that the TomTom doesn't pick up time setting
changes (e.g. to 'Summer Time', when 1 hour is added).

I had always assumed that because the device knows exactly where it
is, it must be in a position to regulate its time setting.
But it doesn't.

Are any if the other sat-navs clever enough to do that?

It need more than just that, it also needs to know what that
country has chosen to do about the adjustments to the local time.

It's not a Tomtom, but the Navigon version 6 PDA based program always
gives arrival time as local time, even across timezones.

There must be easy access to an appropriate Linux time daemon that can do
exactly this, but maybe TomTom's memory is too tight to accommodate it.

That is a much simpler matter when the journey begins and ends in Europe
because all the countries make their seasonal changes together. Let's see
it navigate from London to New York after the USA changes to its Daylight
Savings Time but before European countries change to their Summer Times.

Well there are roads from Poland through Kaliningrad to Lithuania and those
could also have tested this point because Kaliningrad changed its clock one
hour earlier than continental parts of EU countries on 29 March. Poland
(UTC+1) changed at 2am their local time, Kalingrad (UTC+2) changed at 2am
their local time and Lithuania (UTC+2) changed at 3am their local time.

There also needs to be some mechanism to update the data as a
particular country changes its policy. Thats just happened with Australia
this year with summer time extended for a week in some states.
