abbccdda commented on pull request #7116: KAFKA-8715: fix timestamp bug for
static member.id generation
URL: https://github.com/apache/kafka/pull/7116
The bug is that we accidentally used the loaded timestamp for the group
instead of the real current time. Fix is made and unit test to make sure the
timestamp is properly encoded within the returned member.id.
