I so much agree with you on this! Real logic does not apply, it's called government.

If agencies are allowed to talk to one another, finding out why Linux on z works for folks like this org might be helpful? http://www.disa.mil/Computing/Mainframe-Hosting/IBM-LINUX Best Regards, Kurt Acker IBM Smarter Planet, Smarter Data Centers Virtualization and Enterprise System Management Technologies -- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 -- For more information on Linux on System z, visit http://wiki.linuxvm.org/
Re: Bug in cmsfs-fuse?
Hello Mike, Thanks for your detailed report. The CMS file system stores time stamps in local time. The cmsfs-fuse file system has to report time in UTC to the Linux VFS layer. Therefore local time has to be converted to UTC for reading and UTC to local time for writing. IMO this is currently done incorrectly. In case you are interested, we can provide the corresponding s390-tools patch.
