Working with date and timestamp in R language

Описание к видео Working with date and timestamp in R language

There are three basic date and time classes: Date, POSIXct and POSIXlt

Class Date handles dates without times.

Date and POSIXct are internally stored as number of seconds from January 1, 1970.

POSIXlt stores dates and times as a list of components: second, minute, hour, day, month, year, time zone etc.

POSIXct (calendar time) and POSIXlt (local time) represent dates and times.
