The new Rubidium Atomic Clock is equally easy manageable either from the front panel or the intuitive software control panel available for OS X and Windows, connecting via a USB port. The legend grows.

arg. ignore this. Turns out it's all based on misreading the output of sntp. I thought the output showed the correct server time. But it shows the system time and then the dreft in seconds:

sntp nist.netservicesgroup.com

2016 Mar 25 16:28:46.399196 -338.409283

So the iOS time was correct, time.is and time.gov was correct. The Mac was 5 minutes too fast.

Turns out this has to do with some problem with ntpd and pacemaker on OS X mavericks+ that is apparently still a problem. My personal solution was to create a launch daemon to run this terminal command (as root) every 24 hours:

Alarm Clock Editor's Review

Create alarms for your Mac with this handy utility.

One of the biggest things that people – me – do with their computers is keep track of their schedules. I know I'm pretty anal retentive about my calendar. I also know that I can often get lost in my writing when I've got a good topic I'm writing about. Its at times like this, that I'm glad that there are applications like Alarm Clock. It’s a Mac app that will help you remember key events and deadlines.

Alarm Clock is a menu item alarm clock for setting either one-time alarms or repeating alarms. Then choose anything in the iTunes library to wake to: songs, playlists, even podcasts. The application takes care of the rest, even waking the computer from sleep if needed.

Atomic Clock For Mac Os X

You can configure your snooze duration to the length you want. You can even increase/decrease your snooze time right from the alarm window. Plus, if you have an apple remote, you can hit snooze without getting out of bed. If waking up to blaring alarms in the morning isn't your cup of tea, there's an 'easy wake' option that gradually increases the alarm volume over time. All of the settings are end user configurable.

App Pro’s: Easy to use, Free

App Con’s: Functionality is limited to alarms and a stopwatch

Conclusion: Alarm Clock is a simple program, but what it does, it does very well. This is key system functionality that I haven't been able to find in this configuration in OS X, even with Reminders; and I'm glad that this app has found its way to my hard drive. I'm certain you'll like the app as well. The price is certainly right.
