Triquetra notebook

Claudia's notebook is a notebook in which Claudia Tiedemann has recorded entries related to time travel. It has a triquetra on the cover.  

Claudia gave it to Tronte Nielsen.  

Pages

A page with a table was briefly seen, seemingly recording when someone time travels through the tunnel. The first three columns probably signify the three time periods, the fourth column the date and the fifth column the time. The sixth column appears to record mHz / Hz, with all records adding up to 50Hz (the standard frequency of the power grid) except the third row, which adds up to 50,1Hz.
