I have the same question. Could anyone help on this?

Walter's questions are spot-on. You need to answer them before any further progress can be made, as the implementation depends on what you mean by "time stamp", "time servers", "establish connection" and "read time".

Note that you also need to care about latency of connections, number of connections you are making (as to not make a DDOS) attack, and if you can make use of existing infrastructure or methods in place to synchronize time (e.g. broadcast packets on your network that are routed from a time server).

You also need to know what kind of accuracy you are shooting for. That gets into a whole other level of discussion. As well as knowing if you are "right".
