Awk convert from day of year to date

Hello everyone,
I have a file which has day of year in one of the columns (JD=substr($0,72,3)). The bellow scripts shows me the minimum and maximum values of the JD and I would like to convert the JD to date.
Code:
#!/bin/gawk -f
  {
 check=substr($0,1,1)
 if (check == "S") 
 {
  JD=substr($0,72,3);
 {
  if(minJD=="")
 {
  minJD=maxJD=JD
 }
  if(JD>maxJD) 
 {
  maxJD=JD
 }
  if(JD< minJD) 
 {
  minJD=JD
 }
  } 
}
}
END {
today = strftime("%d.%m.%Y")
today2 = strftime("%d.%h.%Y")
time=strftime("%H%M")
print minJD, "  ",maxJD,today,today2,time
 }

Result:
Code:
175    197 17.07.2011 17.Jul.2011 0720

Any help is greatly appreciated

This module provides routines to format dates. They correspond to the libc routines. &strftime() supports a pretty good set of coversions -- more than most C libraries. strftime supports a pretty good set of conversions. The POSIX module has very similar functionality. You should consider using it instead if you do not have allergic reactions to system libraries. GENESIS
