Convert to Unix timestamp — to_unix

Converts a POSIXct datetime to Unix timestamp

to_unix_timestamp(datetime, tz = "UTC")

Arguments

datetime	Either a `POSIXct` datetime value or a character value that can be coerced into such a `POSIXct` datetime value. Expected format: `%Y-%m-%d %H:%M:%S`. If `datetime` is a character value, then hours, minutes, and seconds must be provided explicitly (so, for example, a value of `"2010-01-01 00:00:00"` will work, while `"2010-01-01"` will throw an error).
tz	Character value corresponding to the timezone of `datetime`. Defaults to `UTC`.

A character value that corresponds to a Unix timestamp.

All Unix timestamps returned by this function have a millisecond-level precision.

dt <- "2019-01-01 00:00:10"
