myTimeZone for eBay

I've always had problems knowing where a timezone was at and calculating when an auction was going to end on eBay.

After reviewing a lot of Firefox eBay extensions, myTimeZone is definitely spot on and should be a welcome extension for the avid eBay-er.


myTimeZone automatically converts the time on any eBay page into your timezone. The only thing you need to worry about is purchasing your item at the right time.


The installation of myTimeZone was flawless and since it's a transparent extension, you won't find any trace of it visually on a toolbar or status bar. The only way you'll be able to tell it's working is if you've navigated to an eBay page. It doesn't matter what page it is. If it has a time on it, it'll convert it.


For an extension so small and transparent, myTimeZone has a lot of features packed into it.

Just to give you a taste of what's included in the extension (taken from the page):

  • Automatically converts any dates it finds on eBay pages to your local time. Intelligently adjusts for Daylight Savings time regardless of where you are located! (discussed above)
  • Gives you lots of options to customize the display of dates to be more readable:
  • Use 24 or 12 hour time format with AM/PM indicators
  • Substitute words like "Today" and "Tomorrow" for actual dates.
  • Use the word "at" to separate date and time for better readability.
  • Suppress the display of seconds in the time portion of the date if you like.
  • Choose from 4 different date formats in either U.S. or European style.
  • Add the name of the day of the week to the date.
  • Customize the display of "AM" or "PM" to use periods or lower case if you prefer.
  • Show an asterisk next to times which have been converted to your local time.

A cool feature included is a countdown timer on detail pages. Yes, it actually counts down while you're watching it. You have to activate it through the options.

Two other features are the Total Price Calculation and the Currency Conversion.

The Total Price Calculation adds another column that totals everything including shipping charges.

Currency Conversion can automatically update the exchange rates daily. If your search listings are from different countries, myTimeZone takes search results and converts the amounts into your currency.


When I first loaded the extension into Firefox, I never expected a timezone extension to have so many options. That's what makes myTimeZone so helpful. The more options you add to an extension, the more flexible and valuable it'll be to your users.

myTimeZone configuration screen

The tabs of the configuration dialog are divided into these sections: Date Format, Time Format, AM/PM options, word substitution, price display, and the About box.

Each section allows you the ability to change how you want the extension optimized for Firefox/eBay.

For example, the price display tab has a checkbox to turn on the Add column for Total Price and include shipping. Check this on and the next time you visit eBay, you'll see your changes reflect immediately.


If you use eBay a lot, myTimeZone is the extension to complement other Firefox eBay extensions. However, I didn't add all of the eBay extensions at once to determine if there were any extension conflicts.

Overall, I didn't encounter any problems with myTimeZone. It was stable enough to win an eBay auction for me. Woo hoo with a rating of 5 out of 5.
