我想使用php在数据库中保存正确的日期和时间。 如果我的系统日期错误，那么它会保存错误的日期

I use following coding to save a date in database. Please help me to save correct date and time:

$mysqldate = date('Y-m-d H:i:s'); 

I think your are facing problem for not set default time zone.

Set your time zone

<?php date_default_timezone_set('Asia/Tokyo'); ?>

Here the list of time zone

Time zone list

Now If you try your code now,you will get correct date time.

$mysqldate = date('Y-m-d H:i:s'); 
echo $mysqldate;
