将 Unix 时间戳转换为 Carbon 对象

There are several ways to create Carbon instances described in the Carbon documentation, which is linked at the bottom of the project's README. The relevant section is this:

The final two create functions are for working with unix timestamps. The first will create a Carbon instance equal to the given timestamp and will set the timezone as well or default it to the current timezone. The second, createFromTimestampUTC(), is different in that the timezone will remain UTC (GMT). The second acts the same as Carbon::createFromFormat('@'.$timestamp) but I have just made it a little more explicit. Negative timestamps are also allowed.

So you can just do:

$carbon = Carbon::createFromTimestamp($dbResult['SomeTimestampColumn']);

Did you check the carbon docs? I think this is what youre looking for:

Carbon::createFromTimestamp(-1)->toDateTimeString();

If you really love your fluid method calls and get frustrated by the extra line or ugly pair of brackets necessary when using the constructor you'll enjoy the parse method:

Carbon::parse(1487663764);
Carbon::parse('first day of next month');
