Summary

Lib Dibbler uses constant block time for both L2 and L1 which can change in future.

Vulnerability Details

All the calculation in the LibDibbler is dependent upon the L1 blocktime and L2 block time, which are set respectively to 12 for L1 and 2 for L2, 12 being for now is right value for ethereum, but look at the following chart

so the block time is not a constant thing and keep changing over time.

So if in future if this value changes it will skew the results of the delta

Hence skewing the results for morning temperature and impacting other functions in Field Facet too.

Recommendations

Use setters and getters for these two variables and don't keep them as constants.
