SQL Server 2016's
AT TIME ZONE appears to be nondeterministic. However, I haven't been able to find documentation officially stating this or giving a rationale as to the reasoning behind it.
AT TIME ZONE nondeterministic?
Example Showing Non-Determinism
CREATE TABLE Test ( LegacyTimestamp DATETIME, Timestamp AS LegacyTimestamp AT TIME ZONE 'Eastern Standard Time' PERSISTED );
Returns the following error:
Msg 4936, Level 16, State 1, Line 1 Computed column 'Timestamp' in table 'Test' cannot be persisted because the column is non-deterministic.
