TWRP: Move the valid current time up to trigger fix on more devices.
For example on my device, the LG V20 (US996), the default time
comes back as 2016 which doesn't trigger the fixup code. 
The actual time I picked was pretty arbitrary, but close to
the current date, since we're checking if said date/time is reasonably
accurate without the fixup code.
