Currently each time an record is written to an extra_file we prepend a time-stamp string to the history attribute. Unfortunately in some cases this attribute gets very long. Once it exceeds ~50K bytes adding more records becomes a very slow process (because of NetCDF-3 file format limitations).

This can be resolved by moving this time-stamp from an attribute into a variable, as suggested by the issue title.
