Synchronising emoncms.local & emoncms.org data collection initial start time

I have set up both of the above but due to initial teething problems the start time of data collection of the 2 systems is different; emoncms.org started collecting data at 12:00 March 17 2019 whereas emoncms.local started collection at 00:00 March 13 2019

Is it possible to synchronise the start time for both emoncms when data collection commenced at say 00:00 March 18 2019?

Is this one for @TrystanLea
