use traceroute to find out?
different ip range, different route?
also, ping result depend on your last mile 1st hop ping beside router, example, for adsl streamyx, there is a setting called fast path or interleaved mode with different level at dslam for each port, with fast path, the ping could go as low as around 6ms 1st hop, with highest level interleaved mode, the ping would go as high as 60ms 1st hop, in the end, the malaysia local or nearby country example singapore destination ping would interpolate depend on 1st hop ping, it's not just plus minus + - only.
i ping sgp-2.valve.net 103.10.124.1 valve dota 2 singapore server, the ping result is almost same with your server
https://lg-my-time.samsam123.name.my/ and time server
https://lglass.time.com.my/traceroute doesnt seem to work at time server, but do work at your server with missing result at the middle.
time server 1st hop result from traceroute is 223.28.26.21 ge-1-2-5-er-01-akhmw.ni.time.net.my , while 211.24.220.166 lglass.time.com.my , and 104.21.86.232 lg-my-time.samsam123.name.my and 1st hop 202.184.160.1
My 1st hop ping beside ping around 2-3 ms only so i don't think it will caused the final result inaccurate.
The IP i stated above [61.189.177.70] will get diff result with time server and my side
idk why

I don't think my 1st hop ping will cause around 30ms different aon the last destination
I've checked the BGP path , the AS number is same as my routing
AS9930 - AS6453 - AS4134
Maybe TIME side routing is different from mine?
