I am running DasBlog on a US-based webserver presumably with a US timezone configured (ie GMT -5:00 => GMT -8:00) and DasBlog is configured to use my local timezone for display (ie GMT +9:30).
Any posts submitted on the first day of the month (eg 1st June 2007), cause the archives control to show an entry for that month but the count is one short.
Clicking the month link will show a month view page with the post submitted on the first of that month not shown.
Clicking the month link for the previous month will not show the post either. It is somewhere in between in limbo.
