One hour, has always been one hour, and is now...one hour.

OTOH, some junior pilots dilly-dally with their time...hard-nosed Captains keep these guys in line...make no mistake.
As in... 'get the lead out, or you will be replaced by the standby.'
Crew scheduling tells 'em the same.
Sooner or later (usually sooner) these guys get the message....or, they are pounding the pavement in search of a job.
NB.
The vast majority of junior guys are on the ball...and are an absolute pleasure to fly with...every day of the week.
Full marks for these folks!
