PT120H in Duration Column


Why have all my duration dates suddenly changed to PTxxxxH?

All the duration and start dates are pulled (linked) from another Smartsheet. All was displayed correctly until a duration of one activity was changed in the master. Then all the durations in the sheet above changed to PTxxxH.

I have tried delinking and relinking but no change.

    The only way I have found to sort this out is to delink, save and relink.

    But I still have no idea what the PTxxxxH means or why it happened.

    Does PT stand for Pessimistic Time? Why would Smartsheet add PT?

    The H stands for hours. All my previous durations were in days and it appears Smartsheet has converted the days into hours.

    For example: 120 hours = 5 days

    Hi @john.beardmore

    Thank you for posting screen captures; I checked in with our Support team and they confirmed that other users have reported the same behaviour. They're currently investigating this, as it's not expected, and should have a resolution soon. I don't have an ETA for when it may be fixed, but I do know this is a priority and that they are actively working on it.
