How to get UTC timestamps from OQL

I'm getting some timestamps using OQL, which returns a pretty nasty format: 

"Mon Dec 04 09:00:00 CET 2017"

However, that's not the biggest problem. The problem is that it will always be in server time, which causes that:

• Locally, people get different results based on their timezone;
• Due to summertime, you don't know Mendix' offset to UTC and thus are unable to dynamically convert it to another timezone.
• The abbreviation seems rather useless in conversion, since it's not a unique identifier.

Therefore, I would really like to get the UTC timestamp, rather than in the server time zone. Any chance?
