Help!! Different masjids in the same city has different prayer times.

So, I recently moved to a new country and this is my first Ramadan here. I noticed that different masjid have different times for each Salah. Some differ a lot while others by a few minutes.

For example; fajr (1- 6:08)(2- 6:12). I am confused on which to follow. Especially on Ramadan.

What’s the ruling on such a situation? Any advice would be appreciated.
