Rounding time to nearest quarter hour
datetime, r
Solution
Indeed, an old question with some helpful answers so far. The last one by giraffhere seems to be the most elegant. however, ist not floor_date but round_date which will do the trick:
lubridate::round_date(x, "15 minutes")
Problem
I have a vector of POSIXct values and I would like to round them to the nearest quarter hour. I don't care about the day. How do I convert the values to hours and minutes? For example, I would like the value ``` "2012-05-30 20:41:21 UTC" ``` to be ``` "20:45" ```
