Just following up as I didn't hear back from you, sorry to email you again. I noticed your page findenglishteacher.com/extrapages/useful2.html links to www.timeanddate.com from World Clock. Unfortunately, that site isn't very accessible for the sight impaired. Would you consider adding a link to a more accessible version like www.thetimenow.com which is WCAG 2.0 compatible?
Also, if you ever want to see how accessible a page is, I recommend wave.webaim.org. It is really helpful.
