Editing Flip clock (section)

== Daylight saving time ==
Many vintage digital clocks with split flap displays cannot be wound back, as the flip mechanism operates only in one direction. Instead they must be either wound forward 23 hours to achieve the effect of winding back 1 hour at the end of [[daylight saving time]] or the clock may be stopped (by disconnecting it from power) for 1 hour. However, on some newer clocks, forward and backward time setting is possible. [[GE]] clocks sometimes had this feature. {{Citation needed|reason=It is easier to believe that some clocks allowed moving the hours ahead independently of the minutes, thus making adjustment for daylight savings time simpler.|date=July 2019}}
