setTimezone(string $zone = null) : \Zend_Date_DateObject
Sets a new timezone for calculation of $this object's gmt offset.
For a list of supported timezones look here: http://php.net/timezones If no timezone can be detected or the given timezone is wrong UTC will be set.
| string | $zone | OPTIONAL timezone for date calculation; defaults to date_default_timezone_get() |
Provides fluent interface
getGmtOffset() : integer
Return the offset to GMT of $this object's timezone.
The offset to GMT is initially set when the object is instantiated using the currently, in effect, default timezone for PHP functions.
seconds difference between GMT timezone and timezone when object was instantiated
_getTime(integer $sync = null) : integer
Internal function.
Returns time(). This method exists to allow unit tests to work-around methods that might otherwise be hard-coded to use time(). For example, this makes it possible to test isYesterday() in Date.php.
| integer | $sync | OPTIONAL time syncronisation value |
timestamp
mktime(integer $hour, integer $minute, integer $second, integer $month, integer $day, integer $year, boolean $gmt = false) : integer|float
Internal mktime function used by Zend_Date.
The timestamp returned by mktime() can exceed the precision of traditional UNIX timestamps, by allowing PHP to auto-convert to using a float value.
Returns a timestamp relative to 1970/01/01 00:00:00 GMT/UTC. DST (Summer/Winter) is depriciated since php 5.1.0. Year has to be 4 digits otherwise it would be recognised as year 70 AD instead of 1970 AD as expected !!
| integer | $hour | |
| integer | $minute | |
| integer | $second | |
| integer | $month | |
| integer | $day | |
| integer | $year | |
| boolean | $gmt | OPTIONAL true = other arguments are for UTC time, false = arguments are for local time/date |
timestamp (number of seconds elapsed relative to 1970/01/01 00:00:00 GMT/UTC)
date(string $format, mixed $timestamp = null, boolean $gmt = false) : string
Internal mktime function used by Zend_Date for handling 64bit timestamps.
Returns a formatted date for a given timestamp.
| string | $format | format for output |
| mixed | $timestamp | |
| boolean | $gmt | OPTIONAL true = other arguments are for UTC time, false = arguments are for local time/date |
getDateParts(mixed $timestamp = null, boolean $fast = null) : array
Internal getDateParts function for handling 64bit timestamps, similar to: http://www.php.net/getdate
Returns an array of date parts for $timestamp, relative to 1970/01/01 00:00:00 GMT/UTC.
$fast specifies ALL date parts should be returned (slower) Default is false, and excludes $dayofweek, weekday, month and timestamp from parts returned.
| mixed | $timestamp | |
| boolean | $fast | OPTIONAL defaults to fast (false), resulting in fewer date parts |
calcSun(array $location, boolean $horizon, $rise = false) : mixed
Calculates the sunrise or sunset based on a location
| array | $location | Location for calculation MUST include 'latitude', 'longitude', 'horizon' |
| boolean | $horizon | true: sunrise; false: sunset |
| $rise |
