In my reciept, that guy has written as "10th october PM 5.30"

Here PM comes in front of 5.30, does the arab guys write like that or PM stands for anything else ?

I am in little bit confusion to go in the morning or evening, because once again they should not tell me to come after one month.

Anyway tomorrow I will update you the scanned copy of my reciept, so that you can also give me a suggestion based on that.
