33 Are you saying that scripts which do mail correctly (i.e. by themselves)
34 work fine?
35
36 But when you rely on crond to send the mail by grabbing STDOUT, then the
37 time is wrong, and that this is consistent?
38
39 That would point to something with crond and would need a few tests such
40 as what happens with other crons from other users, what happens when you
41 downgrade cron and then test?
42
43 I'm assuming you use vixie-cron. Correct?
