The Audit History record for the update to table “Insp” can be found at EventTimeStamp: 4/16/2018 5:53:47 PM
and the workflow rule can be found at EventTimeStamp: 4/16/2018 5:53:57 PM.
The date/time values in these Audit History records are in GMT time while the date/time values in the workflow rule email are in local time. In the Audit History record for the workflow rule you can see the date/time values that are displayed in the workflow email. That will allow you to confirm the match up between the workflow email and the Audit History record.
The Audit History record for the update to table “Insp” contains a ChangeTimestamp value in the “ModifiedDate” field of ‘04/09/2018 12:56:53’. I suspect that ChangeTimestamp value is correct.
The Audit History indicates that the user last did a sync at ‘4/9/2018 10:29:40 PM’. It looks like the user changed the record on 4/9/2018 but did not sync the change until 4/16/2018.
This is reinforced by the AppTemplate Version of ‘1.000959’ contained in the Audit History record for the update. That was the current AppTemplate version on 4/9/2018. Had the user done a sync after 4/12/2018 they would have received AppTemplate Version ‘1.000960’ or later.
