VIIRS VNP46A2 timestamp acquisition time

In the VNP46A2 metadata, the acquisition times are all the same e.g:

RangeBeginningTime': '00:00:00.000'
RangeEndingTime': '23:59:59.000'

Is there any way to find out for a given tile/area what time the actual image was taken?

This is because VNP46A2 is a daily products containing observation for the 24h period. You can find UTC-Time parameter in VNP46A1 product that lists UTC view time (the time of data acquisition). For more information consult product users guide at:
