Use calendar:universal_time/0

universal_time() -> datetime()

datetime() = {date(), time()}
date() = {year(), month(), day()}
time() = {hour(), minute(), second()}

Like this

{Date, _Time} = DateTime = calendar:universal_time()

You can refer to this question to convert datetime() to unix timestamp. You'll just need to convert timestamp to seconds since 1970/01/01:

Seconds = calendar:datetime_to_gregorian_seconds(DateTime) - 62167219200,
%% 62167219200 == calendar:datetime_to_gregorian_seconds({{1970, 1, 1}, {0, 0, 0}})

@Geek then first state in your question that you ask for date in seconds since 1970 to begin with. – Lol4t0 Oct 09 '15 at 08:50
