If you've ever needed to keep track of the time in more than one city, you'd know how much of a hassle it is to have to convert the time between one place and another. I've always found it a pain to try and remember the number of hours I've to add or subtract, and if DST is in effect or not. That's where City Time comes into play. It tells you the times in many different cities, saving you the hassle of having to convert the times yourself.

CityTime has a database of 130 cities from which it draws its resources. Of these 130 cities, you can pick up to 5 cities that will show up on the main CityTime screen. One of these 5 cities has to be designated your 'Home City'. CityTime will prompt you to pick a Home City the first time you run the app. If, however, you find you need to select a different Home City somewhere down the road, that can be easily done by going to 'Options - Select Home City'. If you can't find your home city amongst the database of 130 cities, you can easily use the 'Edit Cities' function and create, duplicate or import any new city/cities which you require. Cities are imported via Memo Pad, and the import files for the procedure can be obtained from Code City's website.

Installing and running CityTime is simple. There are no external databases to mess around with during the installation, and the interface is clean and easy to maneuver around. The upper half of the main screen is taken up by a world map with a day/night plot. The lower half of the screen shows you the times in 4 cities that you specify. The day/night plot moves from right to left, and it tells you when a city is experiencing daytime or night time. It's a very handy map to have around, since it can tell you just at a glance which cities' (or, if you aren't that great in Geography, which continents!) inhabitants are awake and which aren't. Tapping anywhere on the map brings up a display that shows the time and name of the nearest city.

Your 'home' time is shown at the top right corner of the screen. I didn't quite like this arrangement since the home time ended up occupying the tiniest screen space amongst the other city times, which made it somewhat harder to see. If it were in slightly larger font, that would be perfect. Tapping on the home time display gives you the current day and date of your home city.

DST is well handled by CityTime. In the database of cities, the cities that are known to employ DST have pre-set DST occurrence dates. These 'auto' DST times, as CityTime calls them, can easily be edited by going to 'Options - Edit Cities'. For my review, all the instances of DST that I used were accurate, and I didn't have to tinker around with the edit function. On the main screen, cities with DST are shown as having a little star next to the city's name.

You can customize CityTime to your own preferences. The Display Period, Plot Redraw, Twilight Area, and GMT Format can all be changed to suit your liking. Other functions include a Time Difference calculator, as well as a Sun Rise / Set information screen.

The best part about this new version of CityTime is the color version for the IIIc. The use of color in this app has certainly enhanced its aesthetic value, and it's just a pleasure to look at! Code City has employed the use of color very effectively in this new version of CityTime, and the color enhances the usability of the app.

One qualm I have about CityTime is that it takes up quite a fair bit of RAM on the Palm. The color version is close to 200kb, while the grayscale version is about 120kb. However, it's best to keep in mind that many other world clock apps are equally large in size due to the amount of information stored in the databases.
