I don't think 12:48 is one of their usual prayer times.
Muslims observe the formal prayers at the following times:
Fajr (pre-dawn): This prayer starts off the day with the remembrance of God; it is performed before sunrise. Dhuhr (noon): After the day's work has begun, one breaks shortly after noon to again remember God and seek His guidance.
'Asr (afternoon): In the late afternoon, people are usually busy wrapping up the day's work, getting kids home from school, etc. It is an important time to take a few minutes to remember God and the greater meaning of our lives.
Maghrib (sunset): Just after the sun goes down, Muslims remember God again as the day begins to come to a close.
'Isha (evening): Before retiring for the night, Muslims again take time to remember God's presence, guidance, mercy, and forgiveness.
