To make a time of day combine the hour from above with the minute.

Examples:

yoji sanjunifun - 4:32
goji gojuuhappun - 5:58

One can also use the term han for half past the hour. Han literally means half.

Example:

hachiji han - 8:30

To distinguish between A.M. and P.M. use the terms gozen and gogo. A.M. is gozen and P.M. is gogo. Note that gozen and gogo should appear before the time, not after.

Examples:

gogo sanji - 3 P.M.
gozen niji juuippun - 2:11 A.M.

To ask what time it is now, the phrase Ima, nanji desu ka. can be used.
