a question about time

[Heidi]

Dear friends,

"I'm meeting Terry in fifteen minutes at five o'clock."

Does it mean that it's four forty-five, and I'm going to meet Terry at five o'clock?

Thank you!

Yes, it must be 4.45 if it's going to be 5.00 in 15 minutes.

I would add a comma to that sentence, as shown above.
