A remote-team message saying tomorrow at three can leave three fields unresolved: date, time, and time zone. Treat the reply as information to validate, not a Boolean that makes the whole calendar invitation correct.

A casual confirmation

Are we still on for tomorrow?

This asks whether an existing plan remains valid. It is useful with friends or familiar colleagues; it is not a universal formal booking-confirmation template.

Make the missing fields explicit

Could you confirm the date, time, and time zone?

Compare the answer with the calendar invitation. A date-only value is not an instant. If you are building a scheduling UI, show the zone beside the displayed time and preserve the zone or offset in the relevant data model. Do not invent a conversion from a bare three o’clock. This is a small design reminder, not a production calendar implementation.

Practise the branch, not just the sentence

In a fictional exercise, one person says the plan is unchanged. In a second round, they ask to reschedule. Respond with What time works for you? and reconfirm the resulting date and zone.

Use invented dates and details. Do not publish meeting tokens, private calendar links, or client information in an example.
