Fields

  • timestampDateTimes

    Moment the message refers to, in UTC. FIT stores it as seconds since the FIT epoch (December 31, 1989, 00:00:00 UTC); decoders usually expose it as a regular date.

  • timestampMsUint16ms

    Millisecond part of the timestamp, for sub-second precision.

  • Time between two consecutive samples.

  • accelXFloat64[]mG

    Accelerometer samples on the X axis.

  • accelYFloat64[]mG

    Accelerometer samples on the Y axis.

  • accelZFloat64[]mG

    Accelerometer samples on the Z axis.

  • High resolution timestamp, ticking 32,768 times per second, used to align raw sensor samples.

  • mesgNumString

    Global message number identifying the kind of message. Decoders use it to know which profile to apply to the data.
