use of ntp service

Question

I'm developing an app that needs to control real time in any location on the Earth and do something when time comes. At the same time not to rely on system time because user can easily change it.
Does anybody have an experience of implementing "sntp/ntp" service on android device or is there any other solution to do it? Thanks
