Hi Tom, They are in UTC+8. However next week when they release the new schedule it should just be in plain regular UTC time to make it less confusing. In the mean time use this calculator to convert it https://www.timeanddate.com/worldclock/converter.html?iso=20190423T040000&am... . As of right now its only on late at night here in NA during east coast passes roughly past 1:00 AM in the morning.
