**Issue in `TimelineHistoryHelper.getLatestModifyTimestamp`**

The `Timestamp timestamp = Timestamp.valueOf("0000-00-00 00:00:00.000000000");` line consistently triggers an error.

Code snippet:
```java
protected static Timestamp getLatestModifyTimestamp(Persistable paramPersistable) throws WTException {
Timestamp timestamp = Timestamp.valueOf("0000-00-00 00:00:00.000000000");
ArrayList<LifeCycleManaged> arrayList = new ArrayList();
arrayList.add((LifeCycleManaged) paramPersistable);
HashMap hashMap = LifeCycleHelper.service.getHistoryForIterations(arrayList);
if (!hashMap.isEmpty()) {
ArrayList<LifeCycleHistory> arrayList1 = (ArrayList) hashMap.values().toArray()[0];
for (byte b = 0; b < arrayList1.size(); b++) {
LifeCycleHistory lifeCycleHistory = arrayList1.get(b);
if (lifeCycleHistory.getModifyTimestamp().after(timestamp))
timestamp = lifeCycleHistory.getModifyTimestamp();
}
}
return timestamp;
}
```

**How to resolve the above issue**

"Today you should not (normally) have a need for a Timestamp object. The java.sql.Timestamp class is long outdated. Once we used it for transferring timestamp values with nanosecond precision to and from SQL databases. Today we use the Instant class for this instead. Instant is one of the classes of java.time, "

no.  bug is in windchill source code.we can't change its code.the version of jdk is 7.

Hi @TB_10966080 

So what do you need from community if you refuse the help idea from @rleir 

PS> you can change the code, but it is on your own risk.

You didn't understand me. There is a problem with the WindChLL source code, not with the code I wrote myself. The code posted on it is the official WindHill source code, using JDK 7. Please help solve the problem

Hi @TB_10966080 

If it is Windchill class you can decompile it change it and use it in the Windchill.

You have to overwrite OOTB files. 

You can do it, but as I wrote, it is on your own risk.

Hi @TB_10966080 

What Windchill version do you use?

In my Windchill the helper does not contains the row with zeros. there is just null

Windchill 12.0.2.0 library

  protected static Timestamp getLatestModifyTimestamp(Persistable var0) throws WTException {
    Timestamp var1 = null;
    ArrayList var2 = new ArrayList();
    var2.add((LifeCycleManaged)var0);
    HashMap var3 = LifeCycleHelper.service.getHistoryForIterations(var2);
    if (!var3.isEmpty()) {
      ArrayList var4 = (ArrayList)var3.values().toArray()[0];

      for(int var5 = 0; var5 < var4.size(); ++var5) {
        LifeCycleHistory var6 = (LifeCycleHistory)var4.get(var5);
        if (var1 == null || var6.getModifyTimestamp().after(var1)) {
          var1 = var6.getModifyTimestamp();
        }
      }
    }

    if (var1 == null) {
      var1 = var0.getPersistInfo().getModifyStamp() != null ? var0.getPersistInfo().getModifyStamp() : var0.getPersistInfo().getCreateStamp();
    }

    return var1;
  }

 So you can copy the class from the WNCWEB.jar 

recompile it

correct it 

remove it from WNCWEB

place your class to the codebase correct place same as it was in the WNCWEB.jar

and everything will work 😄
