In bash, the following works for setting the date from a UNIX timestamp ( seconds from the epoch ):
date +%s -s @`date +%s`
In Busybox, this does not work. How can I do the same for the date command with Busybox? Thanks.
Try
date @`date +%s`
I don't think it's got anything to do with bash.
Busybox's date
command is a lightweight version of the more classic GNU/FSF date
date -su `date ++%s`
to properly set the clock with the resultant UTC string.
