Funny thing happend on the way to earth, plants are stuck in max blooming 12/12.
I have a automated system relayrunner, plants are stuck in a 12/12 blooming sequence. In nature a plant starts do bloom when the days get shorter. and the nights get longer. Muther nature has been stuck that way for a few million years on earth.
Things I have found out , feb extra day every 4 years , it still harvest in 63 days. When the extra one second was added a few years ago. I harvested my plants 1 second sooner.
Bottom line its not nice to screw with muther nature.
I do not think anything has changed over the last 35 years , but someday , maybe.
You can have your computer check in with the time standards once a week, so you do not loose any growing time. ( computer clocks need to be updated every so often)
Grow for piece , and peace on earth, but do it on a blanket, the sands of time got stuck in weird places.
