Description of problem: version 4.2.4-6.1 Hwcert team is using web service to search bugs, but sometimes, we met with "Can't call method "iso8601" on an undefined value at Bugzilla/WebService/Server.pm line 69". After looking into this, I Found the cause was delta_ts = "0000-00-00 00:00:00". So the code of datetime_format_outbound in Bugzilla/WebService/Server.pm need to improve. $time could be undef. Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Should not error Expected results: Additional info:
Do you have an example bug number (or search call) that shows this? I cannot find any bugs with a delta_ts of 0000-00-00.
No, I don't have one now. That date made our tools crash, so we fixed it by changing the delta_ts. I know that case is quite rare, but it could be true.
If you come up with an example to reproduce the error, we can look into it. Until then, I'm marking this bug as WORKSFORME.
