Created Column in changegroup table

[Stephen Costanzo]

I was curious if the Created column in the ChangeGroup table was in UTC or the local time of the change. If it is local, how does one convert it to UTC?

When I pull the changelog via the REST API, the value I get back for the time is returned as 2018-01-29T10:18:20.293-0800 so I'm assuming that it's available from the column in some manner. FYI - the time of the change was 1/29/2018 10:18:20 Pacific Standard Time

Thanks
