date -u 1407697765
time 1407697765 -> 1407697765.0 settimeofday failed Bad file number
busybox date -s @1407697765
date: can't set date: Operation not permitted
I don't feel that I'm doing everything right (especially when
date -u) but it looks like I have no permission... I'm trying it through adb shell
Why do I get these errors and how to set date through shell?
