Fix WordPress UTC Time not correct issue

[taojing10]

in wp-includes/functions.php, look for

case 'timestamp':
	return ( $gmt ) ? time() : time() + ( get_option( 'gmt_offset' ) * HOUR_IN_SECONDS );

change to

case 'timestamp':
	//return ( $gmt ) ? time() : time() + ( get_option( 'gmt_offset' ) * HOUR_IN_SECONDS );
	return ( $gmt ) ? strtotime(gmdate('Y-m-d H:i:s')) : strtotime(gmdate('Y-m-d H:i:s')) + ( get_option( 'gmt_offset' ) * 3600 );

This issue because of php timestamp function.

Hi @taojing10,

Can you clarify what issues you are seeing are?

time() is always expressed as a UTC offset, it's timezone independent. Theoretically, gmdate() should be returning the same date as time() is in your example here.

I suspect the situation you're experiencing may be a mismatch between server timezones and your PHP configuration, but it's not clear from your report if this is indeed the issue you're experiencing.

I would like to note that feeding timestamps into any date function that takes "fuzzy" input should not be done, because significant portion of timestamps is ambiguous for PHP date parser and will crash.

On ticket overall — not clear what is it the issue is and what is it trying to fix.

Ah, wait, I didn't read gmdate() call there correctly. Still strtotime() and other freeform parsing is usually asking for trouble.
