Surprised to see how the Request Tracker log file grew so fast with 1Gb in a month.
Anyway some of the recurring items on the log file is the error below:
[warning]: Invalid date formatter ‘{ Format = “ISO”, Seconds => 0 }’, falling back to ISO (/opt/rt4/sbin/../lib/RT/Date.pm:633)
After some checking it shows coming from the RT configuration in RT_SiteConfig.pm found under /opt/rt4/etc/ folder.
The DateTimeFormat configuration seems to be causing it:
Set($DateTimeFormat, ‘{ Format = “ISO”, Seconds => 0 }’);
The Seconds => 0 must be causing as it could not be resolved
Changing the RT configuration to:
Set($DateTimeFormat, {
Format => ‘LocalizedDateTime’,
Date => 1,
Time => 1,
DateFormat => ‘date_format_short’,
Seconds => 0
},
);
Then restart the httpd service and checked the RT logs.
The message is now gone and everything is working okay.
