| 15 | * Utility class that wraps date/time related PHP functions. Using this class can |
| 16 | * be easier than using `date`, `time`, `date_default_timezone_set`, etc. |
| 17 | * |
| 18 | * ### Performance concerns |
| 19 | * |
| 20 | * The helper methods in this class are instance methods and thus `Date` instances |
| 21 | * need to be constructed before they can be used. The memory allocation can result |
| 22 | * in noticeable performance degradation if you construct thousands of Date instances, |
| 23 | * say, in a loop. |
| 24 | * |
| 25 | * ### Examples |
| 26 | * |
| 27 | * **Basic usage** |
| 28 | * |
| 29 | * $date = Date::factory('2007-07-24 14:04:24', 'EST'); |
| 30 | * $date->addHour(5); |
| 31 | * echo $date->getLocalized("EEE, d. MMM y 'at' HH:mm:ss"); |
