TimeLeft for Wine for Mac

From NesterSoft:

TimeLeft is a clock, countdown, Web countdown, work days and work hours countdown, reminder (including Moon phase reminder), alarm clock, stopwatch, timer, desktop sticker, eBay auction watch, and time synchronization utility. TimeLeft uses Winamp skins to show digits and text. Reminder offers virtually endless customization options, it can alert you at a specific moment or run periodically, remind you before a specified event or keep on reminding you after it.

The reminder can show a message, play music, open a link or document, or shut down your PC. The Countdown feature lives on your desktop and shows the amount of time left until (or that's passed since) the specified event. Watching the seconds ticking away it makes some glad event so much closer. You also can put your countdown on a Web page. Version 3.39 includes scripting, sticker resize, various fixes and improvements.
