I saw a whole bunch of these in my "daily run outputs" this morning,

  Checking for rejected mail hosts:
  -1d: Cannot apply date adjustment                                         
  usage: date [-nu] [-d dst] [-r seconds] [-t west] [-v[+|-]val[ymwdHMS]] ...
              [-f fmt date | [[[[[cc]yy]mm]dd]HH]MM[.ss]] [+format]            

On 3.4-STABLE and 4.0-STABLE machines.

It took me a few minutes to catch on, but I eventually realized the
problem must be that the date command tried to back up into the "lost"
daylight savings time hour. The 0200-0259, April 2 that never
happened.

Isn't this broken behavior? Shouldn't one get,

  % date; date -v-1d
  Mon Apr  3 02:01:00 EDT 2000
  Sun Apr  2 01:01:00 EST 2000

Since that actually is one day (24 hours) earlier. Right now I get
this type of response,

  %date; date -v-2d
  Mon Apr  3 10:31:47 EDT 2000
  Sat Apr  1 09:31:47 EST 2000

I don't have time to look into details right now. PR 17750
addresses this problem, but not correctly.
