Update file_create_date on write
Feature Request
Opening an NWB file in any mode except 'r' should add an entry with the current date and time to NWBFile.file_create_date. It would be better if this could be changed only upon modification to the file, but with how h5py works, this does not appear to be trackable. (One could just do dataset[()] = some new data without calling io.write).
If this is not doable, I suggest 1) changing the documentation and 2) changing the variable type from array of datetimes to a single datetime.
Problem/Use Case
NWBFile.file_create_date is intended to store a record of the date and time an NWB file was created and all subsequent modifications made. But this is currently set to a list containing one element - the creation date. The list is never subsequently changed.
