Cortana and date time problems with latest build 8.10.14157.200

[daniel_leavitt2000]

I am in Thailand with a SIM cardless L920 locked to AT&T. I have been using it on Wi-Fi to read mail and chat via Line. I updated to latest build on Wi-Fi and have been having problems. Date and time will don't set automatically (I think because they're is no SIM, but Cortana will not refund to voice commands and the battery is draining very fast. Any suggestions?
