Methods
Constructs the validator and sets validation options
Push a new Result onto the Result stack and return it in order to fix cyclic calls to a single validator.
Pop and return the current Result from the stack and make $this->result point to the last Result again.
Get the current Result for this validation invocation. Use this inside your isValid() implementation to e.g. merge results together into the current one.
Checks if the given value is valid according to the validator, and returns the Error Messages object which occurred.
Adds errors if the given DateTime does not match the set boundaries.
Creates a new validation error object and adds it to $this->errors
Calculates a DateTime object from a given Time interval

Result
validate(mixed $value)
Checks if the given value is valid according to the validator, and returns the Error Messages object which occurred.
protected void
isValid(mixed $dateTime)
Adds errors if the given DateTime does not match the set boundaries.
latestDate and earliestDate may be each
In general, you are able to provide a timestamp or a timestamp with additional calculation. Calculations are done as described in ISO 8601 (2), with an introducing "P". P7MT2H30M for example mean a period of 7 months, 2 hours and 30 minutes (P introduces a period at all, while a following T introduces the time-section of a period. This is not at least in order not to confuse months and minutes, both represented as M). A period is separated from the timestamp with a forward slash "/". If the period follows the timestamp, that period is added to the timestamp; if the period precedes the timestamp, it's subtracted. The timestamp can be one of PHP's supported date formats (1), so also "now" is supported.
Use cases:
If you offer something that has to be manufactured and you ask for a delivery date, you might assure that this date is at least two weeks in advance; this could be done with the expression "now/P2W". If you have a library of ancient goods and want to track a production date that is at least 5 years ago, you can express it with "P5Y/now".
Examples:
If you want to test if a given date is at least five minutes ahead, use earliestDate: now/PT5M If you want to test if a given date was at least 10 days ago, use latestDate: P10D/now If you want to test if a given date is between two fix boundaries, just combine the latestDate and earliestDate-options: earliestDate: 2007-03-01T13:00:00Z latestDate: 2007-03-30T13:00:00Z
