Dear Cygwin community,

I'm beating with my self in order to set up a simple cron job in a
Cygwin environment (setup.exe version 2.738) under Windows server
2003. At first I encountered some difficulties to start cron service
but now it starts correctly and cron logs its run my job.

For information, here what I used to set up cron:

  net user cron_server --Passwd123_ /add /active:yes /fullname:"Cron
Server" /comment:"Cygwin Cron Server"
  net localgroup Administrators cron_server /add
  editrights -a SeAssignPrimaryTokenPrivilege -u cron_server
  editrights -a SeCreateTokenPrivilege -u cron_server
  editrights -a SeIncreaseQuotaPrivilege -u cron_server
  editrights -a SeServiceLogonRight -u cron_server
  editrights -a SeDenyInteractiveLogonRight -u cron_server
  editrights -a SeDenyNetworkLogonRight -u cron_server
  editrights -a SeDenyRemoteInteractiveLogonRight -u cron_server
  mkpasswd -l -u cron_server >> /etc/passwd
  cygrunsrv -I cron -p /usr/sbin/cron -a -n -d "Cygwin cron" -e
"CYGWIN=tty ntsec" -u cron_server -w --Passwd123_

As I said cron starts successfully:

  $ net start cron
  The Cygwin cron service is starting.
  The Cygwin cron service was started successfully.

  $ ps -aef | grep cron
  cron_ser    4072       1   ?  17:33:39 /usr/bin/cygrunsrv
  cron_ser    8860    4072   ?  17:33:39 /usr/sbin/cron

I have installed a job under my current user:

  $ crontab.exe -l
  # DO NOT EDIT THIS FILE - edit the master and reinstall.
  # (/tmp/crontab.5GOjQflUK7 installed on Wed Oct 26 17:31:36 2011)
  # (Cron version V5.0 -- $Id: crontab.c,v 1.12 2004/01/23 18:56:42 vixie Exp $)
  * * * * * /bin/date > /tmp/date.log

But I never see /tmp/date.log file:

  $ ls -l /tmp
  total 0

Here is what I can see in cron events:

  $cronevents.exe
  [...]

Note: I have replace my username by 'XXXXXX'

As you can see cron seems able to run the job but, and I still don't
know why, I cannot see /tpm/date.log file.

Would you have some suggestions ?

I thank you in advance for your help.
Regards.
