HDS2-1740 Issues and Queries

A few queries on HDS2-1740 which I have..

1. How do you enable Timeshift recording (Scheduled Recording in advanced) for a specific time slot in advance.. Didnt find any interface to schedule date & time for recording... 

2. The date & time setting of menu reset itself to an old date on every reboot of device.. Also the GMT setting requires India to be set on +7.30 and not +5.30 hours.. Even there the time clock, gets slower by a couple fo minutes every week.. What is the solution for having proper date time in system.

3. I tried Wi-fi dongle (dlink) on HDS2-1740 but it didnt make any of the network menu Active.. Any specific setting to get it going?

thanks
