Ever since the time changed a month or so ago, I've noticed Mudcat time flip flopping between EST (Eastern (US) Standard Time) and EDT (Eastern Daylight Time). Haven't checked to see whether it depends on which server is hosting mudcat.
And I can never keep straight if I'm supposed to leap forward, slide back, or jump ahead, sit back...
Aside: a good page to have bookmarked if you communicate world wide, as on mudcat:

(though it doesn't know about daylight-saving-time either.)
