Hello Pascal, This is exactly the same situation as primary platform. For some uses you have an alternative by using tag calibrationDateTimeTag 'calt'.
If you set this field by hand, you miss its primary goal which is to identify when profile was first created. If you want to do so anyway, you can read the header, change whatever you want and write back the header. That's why the header struct is defined in lcms2.h > it might be nice if the output ICC would be bit identical each and > every time, Not sure about this. This field is excluded from the MD5 when computing the Profile ID. Anyway the creation time is ignored by CMM. ICC spec seems to prefer time tracking that exact binary files.
