timezone support for changedetection

this issue is related to changedetection but since the fix is in the alpine image of sockpuppetbrowser i create it here.
when using changedetection to check websites for free appointments, it was showing me the appointments in wrong times. I checked the changedetection timezone in GUI settings and it was correct. I realized later that issue is that sockpuppetbrowser does not have timezone support but defaults to some timezone (not the desired one).

workaround: execute below in the container as root
$apk add tzdata
$ln -s /usr/share/zoneinfo/Europe/Brussels /etc/localtime

maybe the tzdata could be added in the image and localtime could be set from the main tzdata in changedetection settings?

thanks
