Translation:It is two o'clock.
I always just put the number. Like "it's 2". But with a couple of the questions it marks me as wrong, and insists that "it's 2 PM" is the right answer, so I put "it's 2 PM" only to be marked wrong, with the correct answer being shown as "it's 2.". Really?
First, PM should be wrong. Nowhere in the Japanese does it imply AM or PM, so that's just wrong. Hmmmmm
