Unnecessary overhead in getdate()

Hello, Just like [i]date(), getdate() without the $timestamp argument uses the current timestamp. The code for [i]date() (https://github.com/php/php-src/blob/master/ext/date/php_date.c#L1276) only makes a system call to time(NULL) when the $timestamp argument is missing. In contrast getdate() (https://github.com/php/php-src/blob/master/ext/date/php_date.c#L1828) always performs a system call to time(NULL) even if $timestamp is supplied by the user. The code for getdate() should mimic what is done for date() to avoid unnecessary system call overhead, hence only call time(NULL) when !ZEND_NUM_ARGS(). Can someone please make the appropriate change? Please apologize, but I simply review code and do not have a proper C development setup that allows me to supply patches or create pull requests.
