> While working on https://issues.apache.org/jira/browse/KAFKA-10062 I realized process method in StreamTask is taking
> wallClockTime as input parameter which is redundant as StreamTask already contains time(https://github.com/apache/kafka/blob/2.5.0/streams/src/main/java/org/apache/kafka/streams/processor/internals/StreamTask.java#L75) field which represents wallClockTime.
> In process method (https://github.com/apache/kafka/blob/2.7/streams/src/main/java/org/apache/kafka/streams/processor/internals/StreamTask.java#L664), wallClockTime can be passed from StreamTask's time field itself. 
> This method was changed as part of pr: https://github.com/apache/kafka/pull/7997. 
> As part of https://issues.apache.org/jira/browse/KAFKA-10062, I believe wallClockTime need not be stored in ProcessorContext(https://github.com/apache/kafka/blob/trunk/streams/src/main/java/org/apache/kafka/streams/processor/internals/AbstractProcessorContext.java#L48) but should be fetched from StreamTask's time field. Reference pr: https://github.com/apache/kafka/pull/9744
