Downlink example for SodaqOne V3 Cattle-Tracker

Dear all,
like explained here https://github.com/SodaqMoja/SodaqOne-UniversalTracker-v3#remote-over-the-air-re-configuration it’s possible to set Alternative Fix interval via LoraWAN downlink.

Do you have a downlink example to set Alternative Fix interval to 1 hour from 21:00 GMT to 5:00 GMT for example?

I don’t understand what I must put in “From” and “To” fields in EPOCH

Thanks
