I am trying to convert a timestamp to a number of seconds and it is not working as intended on a mac. On linux I can run: <code>date -d "2015-06-11 12:39" +%s</code> and I get <code>1434044340</code> as intended. However, when I run that same command on a mac, I get <pre class="prettyprint"><code>usage: date [-jnu] [-d dst] [-r seconds] [-t west] [-v[+|-]val[ymwdHMS]] ... [-f fmt date | [[[mm]dd]HH]MM[[cc]yy][.ss]] [+format] </code></pre> what is the corresponding mac command and/or how can I get the original command to work on a mac?

3 years later :) Try this: <code>brew install coreutils ; echo "alias date=gdate" >> ~/.bash_profile</code> Then run your command
