Logs DQL query to fetch user selected current timeframe

[gcnaidu]

Query: fetch logs, from:now()-2h

Instead of from:now()-2h,k I would like to pass user selected range (Current timeframe) dynamically and fetch logs accordingly

Could you clarify your question? What do you mean by user-selected range and the current timeframe? In DQL you can normally specify a specific selected range.

are you after the TimeframeSelector?
