How to convert Elixir's NaiveDateTime to Unix timestamp
I recently spent more than 20 minutes trying to figure out how to convert NaiveDateTime to Unix timestamp. I tried ChatGPT and Google search without any luck. Fortunately, reading documentation helps and it was hiding somewhere in the docs.
Here is how you do it
iex> current_time = NaiveDateTime.utc_now() iex> unix_epoch = ~N[1970-01-01 00:00:00] iex> # Take a difference between current_time and unix_epoch (both are in NaiveDateTime format) iex> NaiveDateTime.diff(current_time, unix_epoch) 1686099838
