UNIX timestamp (A.K.A. Unix’s epoch) means elapsed seconds since January 1st 1970 00:00:00 UTC (Universal Time). So , if you need the time in a specific TimeZone, you should convert it.
Even though is technically possible, I would recommend alternative ways to get current time (or any other time), such as

time manpage with
man time – you may not get what you expect. You certainly won’t get what you expect if you’re looking for the manpage for
That is, unless you’re looking for different things than I was 🙂
Check the return value of date_default_timezone_get() to see what the default time zone is. The link also lists the ways you can change the value, the preferred being by setting date.timezone in php.ini.
