The initWithString: method previously initialized the underlying JavaScript Date object using the local-time constructor (new Date(year, month, day)).
This caused the resulting absolute time to be corrupted by the host engine's local time zone configuration, effectively ignoring the explicit time zone offset provided in the initialization string.
The implementation was a fundamental violation of the canonical contract, as established by NSDate and to be followed by CPDate.
This commit refactors the parsing logic to use Date.UTC(), guaranteeing that the parsed components are evaluated independently of the host environment.
Additionally, it eliminates a redundant RegExp allocation during pattern matching and updates the API documentation to explicitly state that offset resolution is decoupled from both CPTimeZone and the host's local time rules.
