When I just had a closer look it appears to set the incorrect date as in under 2 minutes from when it is set correctly.
This is the export from the correct date:

This is the jc response when the date is correct
{“devt”:1452783631,”nbrd”:1,”en”:1,”rd”:0,”rs”:0,”rdst”:0,”loc”:”-35.28200,149.12868″,”wtkey”:”xxxxxxxxxxx”,”sunrise”:360,”sunset”:1080,”eip”:0,”lwc”:1501945023,”lswc”:0,”lrun”:[0,0,0,0],”sbits”:[0,0],”ps”:[[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0]]}
This is the result JC response after the date changes to the future
