Please read the documentation on InfluxQL. The WHERE clause can be used to filter data based on timestamp.

SELECT * FROM measurement WHERE time = 1234567890000000000

If value data input double from same timestamp?
Example
Timestamp 1234000, value 7
Timesramp 1234000, value 9

I am not sure what you’re asking. Can you share what you’ve tried so far, and provide some example data and queries?
