Summary of the bug:
Timecode of 59.94 fps content from a Panasonic GH5 is not being read
correctly by newer versions of ffmpeg. Confirmed in versions of ffmpeg
from 2020 and 2022. Works fine in a version from 2018. 2018 ffmpeg version
timecode matches the timecode in the Panasonic XML metadata. Not sure if
x64/x86 might play a role as well.
XML: : <StartTimecode>01:51:38:04</StartTimecode>
ffmpeg 2018: timecode : 01:51:38;04
