Java.util.regex and replacing patterns with function calls

Question

Hi everyone,
I'm in terrible need for help.
Any advice is much appreciated.
I have the following sentence in a file. The sequence of numbers is actually a
date in seconds since 1970. I need to identify the 9 or 10 sequence of numbers
send that to a method that will transate the numbers into a date in a string format.
Then replace it in the file.
Here is an example:
"My name is Peter. Please 1020421277 help me figure this out 108062327. "
using the following block I can convert it to this
"My name is Peter. Please | help me figure this out |. "
[block]
Pattern p = Pattern.compile("[0-9]{9,10}+");
Matcher m = p.matcher("");
String aLine = null;
while((aLine = in.readLine()) != null) {
m.reset(aLine);
String result = m.replaceAll("|");
out.write(result);
out.newLine();
[end block]
So I need to change the above block so that my sentence looks like this.
"My name is Peter. Please 05/03/2002 10:21:17 help me figure this out 06/04/1973 17:18:47. "
The method that converts the numbers into a date is not of a concern because I already have
the code to do that.
If anyone has suggestion, please let me know.
Thanks in advance.

Never mind, I was able to figure it out....
Common2 cm = new Common2();
Pattern p = Pattern.compile("[0-9]{9,10}+");
Matcher m = p.matcher("");
m = p.matcher(s1);
while ((found = m.find())) {
String replaceStr = m.group();
System.out.print("\tReplaceString is: " + replaceStr);
replaceStr = cm.get_date(replaceStr);
System.out.println("\t\tConverted to: " + replaceStr);
m.appendReplacement(buf,replaceStr);
m.appendTail(buf);
----------------- The get_date method in Common2 looked like this ------------------------------
public String get_date(String myString)
String s;
long lsecs = Long.parseLong(myString);
lsecs = lsecs * 1000; // its now milliseconds.
// Determine default calendar and then the offset to GMT.
Calendar localCalendar = Calendar.getInstance();
int offset = localCalendar.get(Calendar.DST_OFFSET) + localCalendar.get
(Calendar.ZONE_OFFSET);
// Take the number of milliseconds subtract the gmtoffset
Date GMTdate = new Date(lsecs - offset);
// Format date
Format myformat;
myformat = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss a z ");
s = myformat.format(GMTdate);
return s;
