This is different across servers, correct me if I'm wrong. What I've coded in is as below:
PDT/PST servers: The available random dailies change at the same time as reset
EDT/EST servers: The available random dailies change 22 hours after reset
AEST/AEDT servers: The available random dailies change 7 hours after reset
If you're on a server that has a difference you should now see something like this on Reputables Minimap tooltip:
If this is incorrect please type /rep dailyTime and post the results (and what you believe the correct time difference is) Should look like this:
To manually change the time difference type /rep dailyTime # where # = the difference in hours
