+#
+# Purpose:
+#   This test validates that a slave's relay log format description event is
+# not used to calculate the Seconds_Behind_Master time displayed by
+# SHOW SLAVE STATUS.
+#
+# Methodology:
+#   Ensure that a slave's reported Seconds_Behind_Master does not point before
+# a time in which we can prove that it has progressed beyond. The slave's
+# relay log events are created using the timestamp at which the IO thread was
+# created. Therefore, after starting the slave's IO thread, we sleep so any
+# proceeding events are forced to have later timestamps. After sleeping, we run
+# MDL statements on the master and save the time at which they are binlogged.
+# Once the slave executes these MDL commands, we have proven that the slave has
+# caught up to this saved timestamp. At this point, if the value of
+# Seconds_Behind_Master points before the time in which the MDL events were
+# logged, it is invalid.
+#
+# References:
+#   MDEV-16091: Seconds_Behind_Master spikes to millions of seconds
