Do we have support for UTC and IST datetime conversion for timeseries?

Your question is not clear. What are you trying to achieve and where is this conversion needed?

We have a graph of Requests vs Time. Our server time is in UTC but the data sent to Signoz is shown in IST. We're getting confused when we're comparing the trend in the graph with our logs as for each time we need to go back 5:30 hrs behind. If we could just convert the time to UTC then the data points and our logs would align.

The time you see is your browsers time.
