How can I change time zone in Legato. time_zone.conf does exist.
You should check this tool;
I read about it however I dont know how to run it.
It says "Run basicBuildLegato_configShell_binlegs to add the host tools to the shell’s executable path."
To be honest I dont know what to do with it
Your should check Configure Shell on http://legato.io/legato-docs/latest/basicBuildMake.html
