The GpsLocationProvider in Android reads /etc/gps.conf in order to determine the NTP server to poll.
The default configuration is:
NTP_SERVER=north-america.pool.ntp.orgXTRA_SERVER_1=http://xtra1.gpsonextra.net/xtra.binXTRA_SERVER_2=http://xtra2.gpsonextra.net/xtra.binXTRA_SERVER_3=http://xtra3.gpsonextra.net/xtra.bin
I've updated my NTP SERVER to read from Singapore's NTP server: sg.pool.ntp.org instead.
