Is this electric or strickly battery operated?

Electric but has a battery back up

How do you change time zones?

According to the instruction manual that came with mine, 1) press and hold the 'sleep', 2) short press the 'reverse' or the 'forward'. Zone 1 is Atlantic Time, 2 is Eastern Time (which is the default setting), 3 is Central, 4 is Mountain, 5 is Pacific, 6 is Yukon and 7 is Hawaiian.

does this alarm clock have to be plugged in?

Stated several times, the radio is electric with a battery backup, so yes, it has to be plugged in.

Any problems charging fire tablet with usb port. Clock radio screamed started going crazy and had to unplug it and plug was extremely hot

I have had no problems and bought a second one after purchasing the first one.
