first visit to alert/notifications/event log pages causes error

[fancy-rabbit]

"not a valid date
this is not a valid date"

clicking the links again and the pages are acting properly.
restart httpd or kill the thruk_fastcgi.pl and visit the pages again(i.e. "alert") and the problem is reproduced.

this is in my httpd error_log. and followed by many catalyst errors.

If there are problems with the timezone, you can explicitly set one with "use_timezone" in your thruk_local.conf

[fancy-rabbit]

I set one with use_timezone = "Asia/Shanghai"
this error still occurs. (use_timezone = Asia/Shanghai without quotes does the same.)

whether I set or not use_timezone, the second time(and later) I visit these pages they're OK, but the first time will fail with
ERROR: Date::Manip unable to determine Time Zone.

sorry. seems it's a mod_fcgid problem and it disappears after upgrading mod_fcgid to 2.3.5 from 2.2
