What timezone to use when querying?

Hey community!

I’m new here and I wrote a query to get the latest transactions and aggregate them, but I want to get the transactions in the last 10 minutes. I know the format:
time: {between: ["2021-06-09T20:10:00", "2021-06-09T20:43:00" ]}
A silly question, but I don’t know the timezone I should use, from my test it looks like UTC but I’m not sure? Moreover, is there is a more generic way to query the last minutes like current_time - 10min.

Thanks in advance!

I am sorry but I don’t think so there is a more generic way to filter the time at the present moment.
