Hi, We have many datasets for which we need to express the precision of the time axis. For example, the OSTIA sea surface temperature dataset contains daily fields. The data are considered "representative" of a particular day, without necessarily being a simple average over the day. At the moment the data are registered to 12:00Z on each day, but this is indistinguishable from an instantaneous snapshot at this time.
I guess it would be possible to express the temporal precision using the "bounds" attribute for the variable in question (http://cf-pcmdi.llnl.gov/documents/cf-conventions/1.4/cf-conventions.ht ml#cell-boundaries), by specifying the start and end of each day as the bounds. Is there a less verbose way of providing this information, perhaps by stating the precision as "1 day/24 hours/whatever" as a single attribute?
