generates vector of time points starting from t with length n and granulation gran (default month). The difference between two timepoints is given by step.
settime generates from a set of vectors a vector of time points. The parameter yr (year) is necessary, the parameters mo (month), dy (day of month), hr (hour), mn (minute), sc (second) are optional. The granulation of the measurement can be changed with the command settimegran. Each value in t
