I am developing a GPRS enabled embedded device.To synchronize time with the network I have to use NTP protocol. The nature of the product is such that I have to Hardcode the NTP server address inside the firmware and I cannot change it in future by any means. The estimated quantity of the devices to be sold is in thousand and location is India.
After googling about NTP servers I am not able to figure out which server should I use. The given link mentions about some incidents caused due to wrong NTP client configurations.
I don't want fall into such trouble please help me choosing correct NTP server Address.
