development version (3.4-RC4)
I just updated the SVN for one of my plugins. The SVN log shows:
Revision: 557150
Author: Workshopshed
Date: 13 June 2012 09:31:59
Local time is 09:48
The update appeared in the dashboard correctly but when the details were rethe "Last Updated" information suggests that it was changed 9 hours ago.
My Timezone is London.
I don't know if this is specific to wordpress or if it's an SVN issue.
The timezone in SVN is WP's server. Not yours :)
So if my server is London and the WP server is also reporting London times then I'd expect the Last Updated to be correct, not 9 hours behind
I actually have no idea what timezone the SVN server uses...
That said, where are you seeing 'Last updated'? On http://wordpress.org/extend/plugins/blogger-importer/ (for example) or...?
From the updates screen of the wordpress dashboard, it said something like
"You have version 1.72 installed. Update to 1.73. View version 1.73 details."
When I clicked on the view details, it launched a popover with a blue box on the right called "FYI" that was where I saw the last updated info.
