[OnePlus 3 & 3T Cross Device Development] :
I really hate if people explain the most obvious points to me. This makes me feel childish. That's why I havn't explained the most obvious points to you. I also assume people know what they are doing and suggesting, if they suggest to alter system files.

If I explain the most obvious points and bare technical basics of your own suggestion, it's not to offend you or make you feel childish, but because your replies make me think you really don't undertsand or know.

NTP means network time protocol. Nearest NTP server means network-wise nearest server, determined by your device's ip adress and dns (domain name service: mechanism to translate FQDN (full qualified domain name) to an IP-Address.

europe.pool.ntp.org is a pool of 1971 (today: https://www.ntppool.org/zone/europe) time servers. Using europe.pool.ntp.org means that the nearest NTP servers from the pool of european servers are returned if the DNS request is returned.

Using pool.ntp.org is the very same mechanism with a pool of 2713 (today: https://www.ntppool.org/zone/@) time server (europe.pool.ntp.org is a subset of pool.ntp.org). Both pooös return the same for the same source ip address (answer may differ if you move from wifi to mobile data in the same location, depending on different network infrastructure for wifi and mobile data, it can also differ. It can also differ because of network load).

Your assumptions and question doesn't make sense: if geographical location isn't needed for the pool europe.pool.ntp.org, it's not needed for pool.ntp.org, neither.

I've assumed you know that europe.pool.ntp.org is a pool rather then a single server, when suggesting to edit a system file.

It's not about performing better for you (though pool.ntp.org will perform better for you, if you travel to outside Europe, obviously), but it's about to find a generic solution working better for all useres. europe.pool.ntp.org ist not the best choice for a user in Brisbane,

Since we are here in the op3/t los 17.1 thread, I use the term "all useres" in the meaning of "all op3/t los 17.1 users worldwide". I thought this is obvious, onviously it wasn't. ;)

It's done by non-cachable dns cascades. The NTP Pool DNS server uses GeoIP data from MaxMind to help choose an NTP server from the Pool. To start learning see:

I realy belive it's better to use the sophisticated ntp.org infrastructure over the qcom specific time server infrastructure. Especially since ntp.org is non-profit and provides the ntpd sftware as foss - compared to qcom propriatary izat (though this technically doesn't matter) If testing proves (<zone>.)pool.ntp.org is as good or better then time.izatcloud.net, I think it's a good idea to chanhe it in the rom (all users will benefit; even you because you don't need to change the system file on every update).

Again: since we are talking in the op3/t los 17.1 thread, "all useres" is refering to all users of op3/t los 17.1 builds. Since we are talking in the op3/t los 17.1 thread "pushing to gerrit" refers to push something like https://github.com/nvertigo/android...mmit/763300838716c791c0c1f53710a7478035db657b to https://review.lineageos.org/q/project:LineageOS/android_device_oneplus_oneplus3 .

I wasn't aware that you strip the context (op3/t los 17.1 thread) and take my words as a general statememt for all isers of all roms/builds. Hopefully this posting is detailed and precose enough to avoid misunderstandings.
