TFS users using the on-premise version prior to TFS 2016 who have set their time zone to a country where daylight saving starts at midnight may receive the below exception when trying to access their product backlogs when day light saving starts:
“The supplied DateTime represents an invalid time. For example, when the clock is adjusted forward, any time in the period that is skipped is invalid. Parameter name: dateTime”
The issue will last for 24 hours and in the mean time users can access their backlog items through the (Kanban) board.
Another work around to unblock themselves is to run the below script on their configuration database.
exec prc_SetRegistryValue 1, ‘#ServiceAgileSettingsClosedItemsAsUnownedDays’, 360
After 24 hours, please revert your change by executing the following script (If not, the burn down chart will show incorrect data)
exec prc_SetRegistryValue 1, ‘#ServiceAgileSettingsClosedItemsAsUnownedDays’, NULL
Sincerely,
VS Online Service Delivery Team
