Very good little application. I see no way to account for daylight-savings-time (aka summer-time). This makes the application off by one hour during daylight-savings-time.

Easy to input ones own locations, although one must have access to latitude/longitude coordinates for this.

Nice, very basic app. Does what it says it does.

There is room for improvement though. Some ideas:

It would be neat to have the option to keep the time scale consistent between locations (i.e. always have the full 24h day range displayed). As it is now, it is a bit difficult to compare different locations, because the scale changes all the time.

Also, the calculate button could be located in closer proximity to the things that it relates to (i.e. the time and date fields).

It is kind of nice to have the current time of day line, but I would find it even more useful if there would be a vertical current day line.

Finally, the display would be prettier if the grid lines would have a constant width (i.e. one pixel). As it is now, some lines appear different than other - probably because of some kind of anti-aliasing / smoothing.

Would be useful if it allowed for the pasting of coordinates into the location preference pane. Kind of a basic task that all programs should have.
