"In your time" or "at your time"?

I have a partner who lives sumptuously in a different time zone.

I've been wondering which is the correct way of putting it:

11 p.m. in your time

or

11 p.m. at your time

Thank you!


Neither works well. In your time suggests that you are referring to your partner's past.

E.g. We sleep earlier these days. 11pm in your time (30 years ago) would have been like 7pm today.

The second doesn't sound idiomatic to my ears.

Try

at 11pm, your time.
