Downloading sdTime 1.3.1 for Mac from the developer's website was possible when we last checked. We cannot confirm if there is a free download of this app available. The program lies within Productivity Tools, more precisely Timekeeping. This Mac app was originally developed by Benton A Vizzier Jr.
From the developer:
sdTime is designed to allow you to see what time it is in various time zones using names that are meaningful to you.
Main features:
- User defined location and group names.
- Compact table view with multiple sort options.
- Analog clock view to any time zone in any group.
- Access to the IANA time zones supported by Mac OS X which includes support for Daylight Savings Time.
- Search for time zones based on country and region names.
You may want to check out more Mac applications, such as Address Book Scrubber, Quote of the Day or Opera Clock, which might be similar to sdTime.
