LinuxQuestions.org - [root] Changing time without using ntp/ntpdate ?

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) ?
