Solar_Filter_ValidateIsoTimestamp::validateIsoTimestamp()
public
bool
Solar_Filter_ValidateIsoTimestamp::validateIsoTimestamp
( mixed $value
)
Validates that the value is an ISO 8601 timestamp string.
Parameters
(mixed)
$value: The value to validate.
Returns
(bool) True if valid, false if not.
Description
Validates that the value is an ISO 8601 timestamp string.
The format is "yyyy-mm-ddThh:ii:ss" (note the literal "T" in the
middle, which acts as a separator -- may also be a space). As an
alternative, the value may be an array with all of the keys for
Y, m, d, H, i, and optionally s, in which case the value is
converted to an ISO 8601 string before validating it.
Also checks that the date itself is valid (for example, no Feb 30).
