Downloading MetricTime 1.0 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. Please check the Mac app with an antivirus before launch as it is downloaded from the developer's website, and we cannot ensure that it is safe. This free Mac application was originally created by Preston Marshall.
From the developer:
MetricTime takes your local machine time and converts it into LMT (Local Metric Time). It makes access to metric time convenient by showing the current time as a status bar item, just like the native system clock. This application lives in your menu bar.
