with my cron job set to -verbose
It is giving me this error message with running the periodic tasks after adding the action stream plugin.
Use of uninitialized value in localtime at lib/MT/Util.pm line 464. (this line will be in multiple times)
Is this an issue?

When I asked in the past the answer was no that it has to do with some of the streams time values being off.
Thanks Jeremy!
I have a similar(?) issue. Although the cronjob is set to run every 30 minutes I'm getting the following error twice every 60 min:
Use of uninitialized value in concatenation (.) or string at //cgi-bin/mt/plugins/WidgetManager/lib/WidgetManager/Plugin.pm line 32.
I know I'm getting the error every 60 min because cronjob errors are emailed to me automatically (something else to fix). Also, if I run run-periodic-tasks from the command prompt I get the same errors.
Is this not really a problem as per the above, or is it something else entirely? As far as I can tell the Streams are being updated OK (although I haven't determined if its every 30, or every 60 min).
Thanks in advance for any help.
Cheers,
Z.
I seem to have found a fix for this now - try this Jason: http://forums.movabletype.org/2008/03/runperiodictasks-action-stream.html.
This has definitely stopped the errors in my cron job.
