Those times seem like either Zulu time airings meaning a universal time standard that s used around the world over the local time zones or it s the run lengths of the episodes It would be likely that back in the late 1980s a runtime of 22 m 15s is likely as today syndicated shows clock in at around 15 m to 18 m today Network shows which clock in at 21 m 30s today were also longer back in the 1980s
