Windows is waiting for the end of the century

I was inspecting the list of timers in a complete memory dump and found that in x64 W2K8 R2 (it may be also in other versions) there is a timer set to fire for the end of our century 2001 - 2100:

1: kd> !timer
Dump system timers
    fffff80001c31b80   f690c4d5 0064364d [12/31/2099 23:00:00.510]  nt!ExpCenturyDpcRoutine (DPC @ fffff80001c31bc0)

Its disassembly shows at that time the following work item will be executed:

1: kd> uf nt!ExpCenturyDpcRoutine
fffff800`01ae81ab 488d0dae991400  lea     rcx,[nt!ExpCenturyWorkItem (fffff800`01c31b60)]

I don’t want to dig myself far into the details here :-) May be someone from MS provides some comments what we should expect at the turn of the century? What should I tell my children to expect if they still run the Windows OS?

PS. Long live the Windows OS! (my the most sincere comment; no pun intended).

    Turn your system clock ahead and find out what it does :)
    WinXP/Win2k3 only lets me go up to Dec 31 2099 12:59 PM, but it does roll over to 2100. But if you change it lower manually, you can never get it back.
