Merge branch 'ta/approxidate-noon-fix' into next

"Friday noon" asked in the morning on Sunday was parsed to be one
day before the specified time, which has been corrected.

* ta/approxidate-noon-fix:
  approxidate: use deferred mday adjustments for "specials"
  approxidate: make "specials" respect fixed day-of-month
  t0006: add support for approxidate test date adjustment
  approxidate: make "today" wrap to midnight
