title: Regex for epoch time in millisecond using java
body: <p>I have this string: </p>
  
  <pre><code>String str = "8240d66c-4771-4fae-9631-8a420f9099ca,458,cross_vendor_certificate_will_expire,1565102543758";
  </code></pre>
  
  <p>I would like to remove the epoch time from the string using regex I've searched the web but I didn't find a suitable solution. 
  This is my code I have so far:</p>
  
  <pre><code> public void createHashMapWithAlertCSVContent() throws Exception {
          for(String item: lstServer) { //lstServer is a list contains names of the CSV files 
              String[] contentCSVStr= CmdHelper.Remote.File.cat(SERVER,INDENI_INSIGHT_PATH + "/"+item).split("\n");//Function to get CSV contents
              mapServer.put(FileUtil.removeExtension(item), contentCSVStr);//Finally I add each String[] to hashmap key is the csv file name and String[] is the content of each CSV file
          }
          Assert.assertEquals(mapServer.size(), lstServer.size());
          mapServer.remove("job");
      }
  </code></pre>
  
  <p>example of possible content:</p>
  
  <pre><code>1. 0,TRIAL,8240d66c-4771-4fae-9631-8a420f9099ca,1566345600000,5,1565102549213
  2. 8240d66c-4771-4fae-9631-8a420f9099ca,0,1565102673040
  3. 8240d66c-4771-4fae-9631-8a420f9099ca,0.0.0.develop,4418,1565102673009
  </code></pre>
  
  <p>EDIT:
  regex might be any location in the string and might exit more than once in the string. 
  length of the epoch time string for sure > 10</p>
