put takes key, data and minutes, not an expiry time. If you want to add an expiry time you'll have to extend it to support that.

https://github.com/laravel/framework/blob/master/src/Illuminate/Cache/StoreInterface.php#L13

I looked at the documentation on Laravel's site for cache and used the example.

http://laravel.com/docs/cache

Using Carbon Objects To Set Expire Time

$expiresAt = Carbon::now()->addMinutes(10);
Cache::put('key', 'value', $expiresAt);

Guess I'm confused. The documentation says it's ok to pass a Carbon Object.

I looked through the code and it doesn't check for a Carbon Object, it just looks at it in terms of minutes. :/

Looks like documentation error since it doesn't work with Carbon.

After a quick test, even though it says the parameter is an INT, I passed in a decimal and the cache works for under 1 minute.

Sorry, it's not a documentation error it was mine. The cache class isn't used directly, it's used through the repository class that adds the support for Carbon, as seen here: https://github.com/illuminate/cache/blob/master/Repository.php#L236 my bad! Not sure why it isn't working for you.

Oh interesting. Ya, doesn't work when I pass the Carbon Object. But it does work when passing a decimal.

Thanks for the help. It's working now, just slightly different than how I wanted. If I have time I'll dig into why it's not working with Carbon.
