■ [Recommended]IftheDHCPserveroffersTimezoneOptions(100/101),thephonewillset
theobtainedtimezoneanddisplaythecorrecttimeonthescreen;thetimewillbe
calculatedbasedonanembeddedTimeZonedatabase,factoringinDST.
■ IftheDHCPserveroffersTimeOffsetOptiononly(2),thephonewillassigntheobtained
timeoffsettothefirstmatchedregioninthelistbutthereisagoodchanceitwon’treflect
theactualgeographicallocation,thereforethedisplayedtimemightbeincorrectinsome
cases.Forexample,ifthegiventimeoffsetisGMT-5andthephoneislocatedinMexico,
thephonewillgetthetime(andtheDSTsetting)fromcentraltimeandnotfromMexico
becauseinGMT-5thereisalsoCentralDaylightTime.
ThenetworkadministratormustmakesurethephonecanaccessthefollowingURLs(tocheck
connectivitywiththeinternet):
https://www.google.com/generate_204
http://connectivitycheck.gstatic.com/generate_204
http://www.google.com/gen_204
Iftheinternetconnectivitycheckfails,a‘NoInternetAccess’warningpopsuponthephone
screen.
