Network Time Protocol is based on a 32 x 32 bit number.  32 bits of digits and 
32 bits of decimals.  It rolls over once ever 136 years.  It will roll over in 

We had a bunch of calix shelves reporting Feb 7, 2036.  Calix kept saying 
things like we were getting bogus NTP etc.  Turns out that their clocks are 
getting set to 0x00000000h by something.  I doubt NTP is reporting that date.

  Yep, this could be like Y2K.  Once the clock rolls, I don’t think NTP yet has 
a field showing epoch number so how do you differentiate between 1900 and 2036?

    Anyone care to guess what is magic about February 7, 2036?
