It’s always a pain to work with multibyte characters; most fonts only support ISO-8859-1 English letters.

Local timestamp problem
Byemino December 10, 2013June 6, 2015

Always check for local time Despite the fact that my server timezone was set correctly, somehow time() was giving wrong ( UTC) hour. So i ended up using wp’s functions to make sure. $now = current_time( ‘timestamp’, 0 ) ;$local_ts = get_the_time(‘U’,$post->ID);
