One travel note for currencies, discounts, units and time zones

Q: Can it convert time zones?

Yes. Write a time and a city, like 9 pm Tokyo in London, or now in Tokyo.

Abroad, simple questions pile up: what is this price in dollars, how far is 12 km, what time is it back home. In Sumico each question is one line, written the way you would say it.
