Javascript snippet needed

I need two small snippets of javascript writing. First snippet: Sits on a web page and print out three times and dates: 1. the time and date at the top of the next hour between 0700 and 1900 (if it's outside these times, it won't print anything at all on this line). 2. the time and date at 8pm tomorrow. 3. the time and date at 8pm the day after tomorrow. Second snippet: A simple countdown timer to the nearest time of the three. So if it's, say, 1430 the times shown by the two snippets will be: 1. 1500 2. 2000 tomorrow 3. 2000 the next day 4. and the countdown will be count from 00 days, 00 hours, 30 minutes. So if it's, say, 1930 the times shown by the two snippets will be: 1. 2000 tomorrow 2. 2000 the next day 3. and the countdown will be count from 01 days, 00 hours, 30 minutes. And if it's, say, 2145 the times shown by the two snippets will be: 1. 2000 tomorrow 2. 2000 the next day 3. and the countdown will be count from 00 days, 22 hours, 16 minutes. Make sense? I'd also like the output to be easily formatted with CSS.
