Garmin FIT Timestamp Converter

While the following may not be useful to most people, in the event that you need to convert FIT file timestamps produced by a Garmin product, this is a time-saver. For whatever reason, Garmin created their own epoch, which began at midnight on Sunday, Dec 31st, 1989 (the year of Garmin’s founding). And as far as I know, all Garmin products log data using this date as a reference. The conversion is simple, just add 631065600 seconds to a Garmin numeric timestamp, then you have the number of seconds since the 1970 Unix epoch, which is far more common (this is the reference used, for example, with the System.currentTimeMillis() call in Java). Hence, the following calculator:

  

Improve Your Swing with the Garmin Impact

Phone with Impact SensorWhether you’re into baseball or softball, the Garmin Impact bat swing sensor is the training aid you’ve been looking for.  The Impact is a bat-mounted sensor that provides measurements and feedback on players’ swings, and makes immediate recommendations for improvement.  It does this via an on-device display, as well as through an accompanying mobile app. Take a look:

The Garmin Impact is powered by a pair of inertial sensors, which together sense the orientation and position of the player’s bat throughout their swing.  This allows it to compute five metrics: bat speed, hand speed, time to impact, elevation angle, and attack angle.  It can also display the full swing path in 3D via a mobile app, with color-coding to indicate areas of high (red) and low (green) bat speed, with impact indicated by a purple line.

Now while other bat sensors exist today, the Impact is the only one to provide an interactive, on-device display, which allows for operation without a phone/tablet nearby.  Just take a swing, then turn over your bat to view your five metrics, as well as a coaching tip (optionally shown every three swings).  This instant feedback allows you to quickly make adjustments to improve your swing or to train for different scenarios.

The Impact mobile app allows you to explore your swings in full 3D detail, and provides images and extended descriptions to the shortened coaching tips displayed on the device.  It also allows users to create and customize multiple bats and batters (as the device itself has only two buttons, entering batter names would be a headache).  The app also enables your phone’s camera to capture swings, with triggering provided by the sensor itself.  All you have to do is select “RECORD” and then point your phone at the batter – the sensor and app do the rest via their BLE link.
