Examples of org.joda.time.DateTime.minusSeconds()

org.joda.time.DateTime.minusSeconds()
Returns a copy of this datetime minus the specified number of seconds.
The calculation will subtract a duration equivalent to the number of seconds expressed in milliseconds.
The following three lines are identical in effect:
```
 DateTime subtracted = dt.minusSeconds(6); DateTime subtracted = dt.minus(Period.seconds(6)); DateTime subtracted = dt.withFieldAdded(DurationFieldType.seconds(), -6); 
```
This datetime instance is immutable and unaffected by this method call. @param seconds the amount of seconds to subtract, may be negative @return the new datetime minus the increased seconds @since 1.1

    DateTime lastSeen = val.getLastSeen();
    
    DateTime now = new DateTime();
    DateTime before = now.minus(rateInMillis);
    //give it 15 seconds before it really should be up to date in the table
    before = before.minusSeconds(15);
    
    if(lastSeen.isBefore(before)) {
      return false;
    }
    return true;
