The incident has been resolved with the release of hotfix 4.95.2 to all training and production instances.
This release prevents the issue from recurring going forward. However, Event dates already recorded in UTC will remain unchanged for now, and any out-of-window queries already triggered by this issue will also remain until corrected. Submissions currently stored in UTC will be corrected at a later date. The timing for this correction has not yet been confirmed.

Identified
Since the 4.95 release, Viedoc Me submissions have been recorded in the database using UTC time rather than the site's local time zone. If the UTC date and the site's local date differ at the time of submission, the Event date in Viedoc Clinic will incorrectly reflect the UTC date instead of the local date. Depending on the data entry windows defined in the study design, this may also result in out-of-window queries. The audit trail in the Viedoc Clinic UI, accessed via "Show History," displays the correct date and time stamp according to the local time zone.
This issue affects both the current and legacy versions of the Viedoc Me application.
The issue has been identified, and a fix is currently being prepared. The fix will ensure new submissions are stored using the site's local time zone, but it will not correct timestamps or out-of-window queries that have already occurred. These will be addressed in a future update.
