it seems like the default HOURS value ('2') for the job that copies bugzilla issues into JIRA (in the ERT project) is not enough to catch the changes. This might be due to the timezones, since the script run by the job and the job itself do not use the same timezone.

for example:

• I created an issue in BZ: https://bugs.eclipse.org/bugs/show_bug.cgi?id=492420 on 2016-04-26 03:07:04 EDT
• I then manually kicked the job with the HOURS value set to 2 (Build #2073 - Apr 26, 2016 3:19:03 AM). (I assume the TZ is EDT here, too.)
• The script output contains the following lines:
  code
  03:19:10 [DEBUG] Current datetime: 2016-04-26 07:19:09.521272 (UTC)

03:19:10 [DEBUG] xmlrpc post:

03:19:10 [DEBUG] buglist get: https://bugs.eclipse.org/bugs/buglist.cgi?status_whiteboard=RHT&chfieldfrom=2016-04-26+04:19
03:19:10 [DEBUG] Found 0 bugzillas to process
code

In the mean time, setting the HOURS value to '6', I was able to get the issue created in JIRA.
