> I wrote a source like this:
> {code}
> public class Foo extends RichSourceFunction<Bar> {
> {code}
> and then did
> {code}
> ctx.collectWithTimestamp(event, event.eventTimestamp);
> {code}
> I got this error:
> {code}
> Caused by: java.lang.UnsupportedOperationException: Automatic-Timestamp sources cannot
emit elements with a timestamp. See interface ManualTimestampSourceFunction if you want to
manually assign timestamps to elements.
> 	at org.apache.flink.streaming.api.operators.StreamSource$NonTimestampContext.collectWithTimestamp(StreamSource.java:97)
> {code}
> After some digging it turns out that {{ManualTimestampSourceFunction}} was renamed to
{{EventTimeSourceFunction}} and apparently the old name still lingers in this error message.
