"In-game breeding hint state that the Sun Dragon can only be bred between 7 a.m. to 7 p.m. (07:00 - 19:00); the time is based on your device's internal clock."
That's not true. I started breeding my dragons at (time according to my phone) 05:58 and ended up with a Sun. Did want a Moon, but got my fifth Sun. So either the time is not at all my device's clock or that rule no longer applies.
I should add I'm in Sweden, CET (GMT+1) and the game tends to start a new day at 19:00 local time. Al events and stuff start at 19:00, not midnight or midday.
Anyone has a hint what time I should breed to get a Moon instead of those lousy Suns? =)
