Ahh, Paragonwiki can display the correct local time (with and without DST):
From paragonwiki.com:
- Open My Preferneces
- then open Date and Time
Then set the Timezone to Fill in from browser.
This works for me. Simple one-click twice a year each time I notice my posting times are one hour off. (i.e. good enough for me, so I can be mostly lazy forgetful :> )
