It is not easy to enter or import date to Gretl system. The only way to enter date is through time series function. It is a weak side in Gretl. It should be a function of enter any date to the system. Any statistic software has function to create date variables as well as create character variables.

Collecting data is depends on measuring observations time. It is not difficult to add creating date function as well as creating character variables.
