General SBML unit question about second multiplier

[smoretti]

Hi

I have a general SBML question about unit tag and the value of multiplier for second.
Most models use mmol_per_gDW_per_hr, they define mole, gram, and second.
They all use exponent="-1" for second because this is "per hour".
But they do not use the same value for multiplier, to go from second to hour.

For BiGG models and some others, the multiplier value is 3600.
For SEED and BioCyc models, the multiplier value is 1/3600.

What is the right value for second in mmol_per_gDW_per_hr ?
The SBML documentation about that is poor.

I posted the same question as a BiGG github issue.
