Release date field warning from official repo

I follow instructions to test 6.10 release from here
But I got a warning when doing ‘apt update’ because release file from official repo has an incorrect Date format.

Date (and Valid-Until) field MUST be in UTC (aka GMT, Z, +0000). Kindly rectify this issue.

By mistake we have non UTC time in the repository which is causing the warning.

We will try to re-index the repo, sorry for the inconvenience.
