https://cql.hl7.org/02-authorsguide.html
Only DateTime values may specify a timezone offset, either as UTC (Z), or as a timezone offset. If no
timezone offset is specified, the timezone offset of the evaluation request timestamp is used.
Having true as expected is not correct with the current expression.
