Keypad authorization — are allowedFromTime / allowedUntilTime in local time or UTC?

Nuki APIs Web

Hi all,

When creating a keypad authorization via the API, the docs state that allowedFromDate and allowedToDate should be sent in UTC, with the device handling the local timezone conversion.

My question is about allowedFromTime and allowedUntilTime (minutes from midnight). Are these calculated from midnight UTC or midnight in the device’s local timezone?

For example, in the UK we’re currently on BST (UTC+1). If these values are expected in UTC minutes-from-midnight, the actual access window on the lock would be off by an hour. If they’re in local time, it lines up as expected — but the docs don’t clarify this.

Can anyone confirm which it is?

Thanks

Dates are always UTC. e.g. an authorization is valid from 1.1.2026 13:00 UTC. For a lock in London with UTC+1 this means from 1.1.2026 14:00 onwards.

Times are always relative to the local time of the lock. E.g. if set to 13:00 - 15:00 an authorization for a lock in London is allowed to lock/unlock between 13:00 - 15:00 London time.

Thanks Jürgen. Just to confirm explicitly - allowedFromTime and allowedUntilTime (minutes from midnight) are based on the lock’s local timezone then, and not UTC?
