In the process of telling time,

... if the hour is anywhere from 1:00 through 1:59,

the verb form is singular

--- pretty much because 1 (one) is singular.

Any other hour (i.e., 2 or more - all the way through 12) is plural,

... so the verb is plural.

The singular verb form with "1" is "ES."

The plural verb form with "2 or more" is "SON."

The question for "What time is it?" uses your Spanish "¿Qué es?" plus "la hora" for "the hour."

Go through the day telling yourself what time it is. Just use the hour for now. If it's 5:15, then tell yourself "It's 5:00."

Do this exercise for a few days, until YOU are can deal with on-the-hour time-telling.
