Incrementing/decrementing the year, prior to 1883, causes 1 year 8 minutes 4 seconds to change(instead of 1 year exactly)

TLDR: watch https://gyazo.com/d24049629e9a43c3b52b81e03ac34abf SUMMARY: When changing the year prior to 1883, an abnormal amount of time changes. Instead of the normal 1 year, 1 year 8 minutes 4 seconds changes on the DATE_TIMESTAMP clock. Only seems to occur prior to 1883 PRIORITY: Low NOTES: The increment/decrement buttons can be unresponsive after several clicks. I assume its probably due to my poor laptop, but it might be worth investigating. You can see it in the clip above.

Expected Behavior

The time delta should be exactly 1 year

Actual Behavior

Its 1year 8 minutes 4 seconds

Steps to reproduce

1.) Change the year to 1883 2.) decrement the year to 1882 3.) The hour and minute clock will incorrectly be altered.

Guess: 1883 is the first year where timezones are used? Before that, you may jump to local mean solar time which depends on your longitude.
