time2spanTxt {Gmisc}

A dense time-span text

Description

When adding a time span text we often don't want to write 3 jun - 10 jun but shorten it to 3 - 10 jun while retaining month and year info only if the span crosses between months or years.

    "{mday(time)} {month(time, label = TRUE)} {year(time)}"),
