Same here on IE8. 
At least the documentation should be updated.

Same here, changed to use toString instead.

toJSON() works in IE8 mode but not real IE8!

function toISOString(date){
    var m = 1+date.getMonth()
    var d = date.getDay()
    return date.getFullYear()+"-"+(m<10?'0'+m:m)+"-"+(d<10?'0'+d:d)
}

@CTimmerm: thanks alot for sharing that routine! Besides just working, it's 
also very concise and yet still makes much shorter work of padding the leading 
zero for the date and month values than other solutions I came across on other 
sites like stakoverflow.

For my part, I would just suggest that your use of the date.getDay() method 
seems to deviate from both JSON or ISO standards... as it's grabbing the "day 
of the week" rather than the "the day of the month". Not sure if you can edit 
that post, but for posterity might be good to replace it with date.getDate().

Thanks again for sharing your workaround! Maybe one of these days I'll find an 
answer why none of the date object to<String> like methods work in system 
jscript tests on my Win7 system.
