From the above table, you can tell that the four don't have same timing for Asr, Maghrib, and Isha. So the timing of your Masjid might conflict with what you see on the internet.
An advice would be that you follow your Masjid's time instead of the timing on the internet. The internet decides their timing from a computer program that might not include many factors. The locals have to include various factors when calculating timing for the Prayers.
