[ZenFone 2 Q&A, Help & Troubleshooting] rlaw:
I have two log files. The smaller one (I believe log for stock recovery) says:

__bionic_open_tzdata: couldn't find any tzdata when looking for localtime!
__bionic_open_tzdata: couldn't find any tzdata when looking for GMT!
__bionic_open_tzdata: couldn't find any tzdata when looking for posixrules!

2 /fastboot emmc /dev/block/by-name/fastboot 0
3 /system ext4 /dev/block/by-name/system 0

The bigger one says which is for twrp says:

__bionic_open_tzdata: couldn't find any tzdata when looking for GMT!
__bionic_open_tzdata: couldn't find any tzdata when looking for posixrules!
