For "Night Unlimited" plan ppl.....if u want to synch ur watch with MTNL's then u cud probably cross-check it from ur Caller ID. Now tht v all know tht da CLIP service from MTNL is free & can be activated by just intimating da Call Centre on 1500. As soon as u rcv ur 1st call after ur CLIP activation, ur Caller ID automatically gets syched with MTNL's clock. Thts bcoz MTNL sends da time information along with da calling number in the first 2 rings. I thot tht this info mite b useful for some & thus shared da same 🙂
