Subject: add scripts/portable_date: wrapper around date for bsd/linux
X-Git-Tag: reboot~558
X-Git-Url: http://git.openwrt.org/?p=openwrt%2Fopenwrt.git;a=commitdiff_plain;h=2f14514a12f708fecbe786e028fb9e3c542907da

add scripts/portable_date: wrapper around date for bsd/linux

date -r $unix_timestamp on bsd is equal to date -d @$unix_timestamp on
linux. To support reproducible builds and not loosing every timestamp
it's required to convert a unix timestamp into human readable timestamp

./scripts/portable_date $unix_timstamp +%T
