If your CSV file contains timestamps you could add them as "case
markers": /Data/Add case markers. However this won't work at
present to encode something like "2006-04-02 15:00:00", even if
you dropped the redundant trailing ":00:00", since gretl displays
only 8 characters of such markers. That's probably something we
should revisit.
Duly revisited. We now support printing of observation labels (or
"case markers") of up to 15 characters. That's enough to handle
timestamps of the form "YYYY-MM-DD:HH". The infrastructure is not
yet in place to recognize the calendrical significance of such
strings, but that will surely follow. This is in CVS and the
Windows snapshot at
