This is an internal function called by some `plot()`

methods. Considering the time series 'units' attribute and the frequency of the observations in the series, the function returns a string with a pertinent time unit. For instance, if the unit is 'years' and the frequency is 12, then data are monthly sampled and `GetUnitText()`

returns the string "months"
