How to change the date time zones in R?

as.POSIXct () changes the date time zones in R. The tz () environment variable sets the current time zone for a location. The time zone can be changed to any time zone by providing the exact city name of the required place. Daylight Saving Time (DST) is the standard time-zone which can be converted to GMT. This recipe demonstrates how to change the date time zones in R.

Step 1 - Change date timezones

Syntax - as.POSIXct(date,format) tx() - it sets the time zones for a date-time date - input date format - required datetime format

d1 <- c("2020-10-15 12:00") t1 <- as.POSIXct(d1,"America/Indianapolis") cbind(US=format(t1),UK=format(t1,tz="Europe/Paris"))

 "Output of code is:"
A matrix: 1 × 2 of type chr
US	UK
2020-10-15 12:00:00	2020-10-15 18:00:00

d2 <- c("2020-10-15 12:00") t2 <- as.POSIXct(d2,"America/Atlanta") cbind(US=format(t2),UK=format(t2,tz="Europe/Athens"))

 "Output of code is:" 
A matrix: 1 × 2 of type chr
US	UK
2020-10-15 12:00:00	2020-10-15 15:00:00

d3 <- c("2020-10-15 12:00") t3 <- as.POSIXct(d3,"America/Seattle") cbind(US=format(t3),UK=format(t3,tz="Europe/Berlin"))

 "Output of code is:" 
A matrix: 1 × 2 of type chr
US	UK
2020-10-15 12:00:00	2020-10-15 14:00:00
