QUESTION
I own a Garmin Vivosport which I use to track my activities and my sleep, and I want to run some analysis on my own heart rate data taken from the FIT files I download via Garmin Connect.
The problem is that I do not manage to align timestamps properly.
A similar question is asked here but I didn't find an answer, nor could comment to add my question.
As explained here, in the FIT files the timestamp information is split into two different variables: a timestamp
which appears every now and then, and a timestamp_16
which is attached to every individual measurement. According to what they say, timestamp_16
contains the lower 16 bits of the actual timestamp, so it should be combined with the higher 16 bits of the previous timestamp
.
I am using data recorded on May 1st 2019. Files cover the 24h of the day, so the first data point is at 00:00 (I checked this in the graphic interface of Garmin Connect and things match). In this file I find this to be the first data entry of interest:

Answered 2019-Sep-07 at 18:46Take the special Garmin epoch into account, it's 631065600 seconds later than the Unix timestamp epoch, the calculations need to happen in that special time (if it was just a normal offset that wouldn't be the case, but these offsets are not strictly additive so the "absolute value" of the time matters). Just subtract 631065600:

Install python-fitparse
You can use python-fitparse like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
