Warning: Use of "localtime" without parentheses is ambiguous
While looking at the log produced by Request Tracker (RT) 4.2.12, I noticed there was a warning message about using “localtime” without parentheses. Here’s the actual error message: [warning]: Warning: Use of "localtime" without parentheses is ambiguous at /opt/rt4/sbin/../lib/RT/Interface/Email.pm line 526. The solution which I found from here, fixed the problem: On line 526 of file /opt/rt4/sbin/../lib/RT/Interface/Email.pm, replace: localtime with localtime(). Thanks to the chap who posted the solution.
