[root] Changing time without using ntp/ntpdate ?

frenchn00b · 07-22-2007, 01:04 PM

I saw that :

Code:

# hwclock --set --date="05/18/2007 18:00:00"
# hwclock --hctosys

could change the date. But it is not working.
what could be failing point I missed ?

also, at the boot, the debian etch is checking the time from server, that couldnt be changed or set to a ntp , and this without affecting/telling that to the BIOS ?

________

I finally found it works with directiva option.
damn, not so easy

rather solved.
I made a script to configure the time and date, starting at boot in /etc/rc2.d/S21myscripttime

with XXXXXXXXXXXXXXXXX number of my city

Code:

elinks "http://www.timeanddate.com/worldclock/city.html?n=XXXXXXXXXXXXXXXXX"  > timetown.htm

cat timetown.htm   | grep CEST > timetown

pyear="$(    cat   timetown | awk ' NR==1 {   print $5  }  '  |  awk  '{ gsub (",", "") ; print  }  '       )"
pmonth="07"
pday="$(cat   timetown | awk ' NR==1 {   print $4  }  '  |  awk  '{ gsub (",", "") ; print  }  '  )"

ptime="$(   cat   timetown | awk ' NR==1 {   print $7  }  '  |  awk  '{ gsub (",", "") ; print  }  '  )"

pheure="$(echo "$ptime" | awk '  {  n=split($1 , vk , ":")  ;  print vk[1]         }                 ')"
echo $pheure + 12 | bc

echo "the text:--$pyear/$pmonth/$pday $ptime--"

if [  "$(cat   timetown | awk ' NR==1 {   print $8  }  '  |  awk  '{ gsub (",", "") ; print  }  ')"   == "PM" ] ; then
	pheure="$(echo $pheure + 12 | bc )"
	pmin="$(echo "$ptime" | awk '  {  n=split($1 , vk , ":")  ;  print vk[2]         }                 ')"
	psec="$(echo "$ptime" | awk '  {  n=split($1 , vk , ":")  ;  print vk[3]         }                 ')"
	ptime="$pheure:$pmin:$psec"
fi
echo "the text:--$pyear/$pmonth/$pday $ptime--"
valuetime="$pmonth/$pday/$pyear $ptime"
echo "the time is $valuetime"
sudo hwclock --directisa --set --date="$valuetime"
sudo hwclock --directisa --hctosys
echo "$valuetime configured to"
echo "the date:"
date
echo "--"

it works.

So, I have two questions:
Is this script harmful ? Is this script affecting the Bios (it looks that not but i am not sure) ?
