Hi,
if you wanna set or sync the correct localtime on tinycorelinux from command line without additional packages you can use this command:
my date before syncing from my dsl-router
date
Tue Sep 22 14:46:47 CEST 2020
syncing the correct localtime:
sudo busybox date -s "$(wget -qSO- INSERT-YOUR-DSL-ROUTER-IP-HERE 2>&1 | grep '^ Date:' | cut -d' ' -f 5-)" -D "%d %b %Y %T %Z"
Tue Sep 22 16:49:10 CEST 2020
