Log Message:
-----------
according to alicia it's better to archive restarts for days 10,20,30
instead of days 1,10,20 because of some interaction between restarting
on day 1 of a month and the history file mechanism.  it's saving 3 days
a month either way and if it's better somehow i'm happy to change the
script.  for simplicity we always archive the 30th even in months with
31 days, and for feb archive day 28 whether it's a leap year or not.
