PHP 和 mysql 中的 Epoch 和 Unix 时间戳转换无法正常工作

Question

1473424835535

http://www.epochconverter.com/

using this which gives exact date

Result : GMT: Fri, 09 Sep 2016 12:40:35.535 GMT

but in PHP

$returnValue = date('d.m.Y H:i:s', 1473424835535);

Result : 22.12.48660 05:32:15

tried in mysql also

select FROM_UNIXTIME('1473424835535', '%Y %D %M %h:%i:%s %x') 

not working

Note : This record is migrated from google api

How to rectify this issue or any method to rectify this issue? Any help will be appreciated.

Answer 1

Your timestamp seems to be in milliseconds , while both php's and MySQL timestamp implementations work on a seconds basis. Solution: divide your timestamp by 1000:

FROM_UNIXTIME(1473424835535/1000,'%Y-%M-%d %H:%i:%s %f') 

Answer 2

As stated on the very site you linked to:

Assuming that this timestamp is in milliseconds

The PHP and MySQL manual states that the timestamp they take is "seconds since Unix epoch".

A quick way to determine whether or not you have a valid timestamp, as defined by the manual, is to count the number of digits. Abovementioned site has a common timestamp listed as well, which you can use for comparison.

Answer 3

FROM_UNIXTIME(1473424835535/1000,'%Y-%M-%d %H:%i:%s %f') is the way os selecting from Mysql and

Proper PHP Way is echo date('dmY H:i:s', (int) 1473424835535/1000);
