Examples

format_datetime("yyyy-mm-dd")
#> [1] "%Y-%m-%d"

format(Sys.time(), "%a %b %d %Y %X")
#> [1] "Tue Nov 19 2024 10:27:45"

# Easy to remember and write the same as above:
format(Sys.time(), format_datetime("ddd mmm dd yyyy HH:MM:ss"))
#> [1] "Tue Nov 19 2024 10:27:45"

# seconds since the Epoch, 1970-01-01 00:00:00
format(Sys.time(), format_datetime("epoch"))
#> [1] "1732012065"
