Testing response times to time.android.com from around the globe reveals in ms:- Europe <30 Middle East <68 North America <150 Johannesburg 183 Buenos Aires 220 Tokyo 226 Sydney 276 Hong Kong 285 Brisbane 295 Mumbai 349 Beijing 4691 Shanghai 4906 Russia n/a Whilst time.android.com is NOT used for GPS NTP, North American time servers are, by specifying north-america.pool.ntp.org as default in the framework, to align with pixel devices. I am assuming similar response times to these servers from around the world. Great for North America and it appears Europe but it does not address the global issue. Also, the pool.ntp.org project forbids both hardware and software vendors from using these default zone names. http://www.pool.ntp.org/en/vendors.html It makes sense, therefore, to leverage the ntp.org's existing 'android' vendor name to make the default ntp server for GPS purposes: 1.android.pool.ntp.org this will return a random but accurate NTP server in close geopraphic proximity to the device. Testing on my own build in the UK seems to improve hot and cold TTFF considerably. Change-Id: I144af45757efa35b32daf034eece6e046d2bde79
