Unix Timestamp in R

Look up the current epoch time and convert between Unix seconds and UTC dates in R.

Get the current timestamp

cat(sprintf("%.0f\n", floor(as.numeric(Sys.time()))))

Timestamp to date

cat(format(as.POSIXct(1700000000, origin = "1970-01-01", tz = "UTC"),
           "%Y-%m-%dT%H:%M:%SZ", tz = "UTC"), "\n")

Date to timestamp

date <- as.POSIXct("2023-11-14 22:13:20", tz = "UTC")
cat(sprintf("%.0f\n", floor(as.numeric(date))))

Open 1700000000 in the converter

How to use it

Copy the current-time example into your R environment to read Unix seconds.
Run the second example to display 1700000000 as a UTC date.
Run the last example to convert that date back into seconds.

POSIXct represents seconds as a numeric value. Supply origin when converting numeric values, and specify tz = "UTC" to keep the result independent of your session.
