Seems that if you persist on finding a solution you will find one
Hereby the steps you need to take:
-Open /opt/etc/asterisk/cdr.conf and change 'usegmtime'
to 'no'. e.g.:
[csv]
usegmtime=no ; log date/time in GMT. Default is "no"
loguniqueid=no ; log uniqueid. Default is "no"
loguserfield=no ; log user field. Default is "no"
-ipkg update
-ipkg install tz
-Goto the /opt/share/zoneinfo folder and find
your timezone location. Copy this location to the
folder /etc/localtime. e.g.:
cp /opt/share/zoneinfo/Europe/Amsterdam /etc/localtime
-Open '/usr/local/.files' and add this line:
/etc/localtime
-To make the change permanent, save it to flash:
flashfs save && flashfs commit && flashfs enable
-Restart Asterisk.
