I use this site for finding the location of Jupiters moons and transits and eclipses of its moons.https://www.projectp....com/jevent.htm
Some have said its inaccurate, but its been accurate for me every time I use it.
What I see however is confusion regarding the conversion of UTC time to our local times. This use to be an issue for me till I just decided I have to understand the conversion times for UTC for my location here in California because so many astronomical events are recorded in UCT Times.
I love to watch the Lunar X events so these are always recorded in UCT Times also, and now the Jupiter moon events so I just had to figure out the conversion.
I do use this for the conversion of time from UTC to Pacific time, then again, we have the issue here of Daylight savings time to standard time, so there's even more confusion for some.https://www.worldtimebuddy.com/
Before you can use this conversion site accurately, you still have to understand it and the dates its listing and understand between the UTC times when it shows one day, and we are in another day because of the differences in time zones.
So far, in every situation I've come across, the astronomical sites that list UTC times for events are accurate within a few minutes.
Hopefully my links give you another option if nothing else. Good luck!
