This works:
DateTime.fromSQL('2018-12-10 16:00:00 America/Denver', { setZone: true })
But when the time zone is UTC it results in an unparsable date:
DateTime.fromSQL('2018-12-10 16:00:00 UTC', { setZone: true })
{
reason: "unparsable",
explanation: "the input \"2018-12-10 16:00:00 UTC\" can't be parsed as SQL"
}
fixed in 9e97c08, will go into the next release
This was released in 1.8.3
