get Time from NTP Server

Add an Option to get the Time from a User-Definable NTP Server. 

Could be a nice Feature for automating work of Server Admins. (small buissness)

Example:
1. get time from Web-NTP like time.google.com,  store in Variable

2. get time from Local Servers,  store in Variable

3. calculate difference of Variables

4. if difference is to high, resync/restart local server

i could use such feature since this is a very repetetive part of my work and id love to do it automated with my phone.

Found no other way to do that
