Countries with more than one time zone on the mainland

Can you guess all the countries with land borders within the country separating time zones?
There must be a land border inside the country separating each time zone with another time zone.
Overseas territories and anywhere overseas are not included.
For the answers to be well-defined, Hawaii etc. cannot be included. Some countries that are collections of islands will also inevitably be excluded.
Daylight Saving Time is ignored.

If daylight savings is ignored, then wouldn't Chile only have one on the mainland? Since the only difference between the two is that one follows daylight saving and the other doesn't?

The time zone in the far south of Chile follows what would be considered summer time all year round. This means that standard time in Chile (winter time, or May - August time, because it is in the southern hemisphere) is one hour behind standard time in the Magallanes. So in winter time, which is considered standard time, it has two time zones.
