RFC3339 Format - LabVIEW-Open-Source/Epoch-Time GitHub Wiki
Non-strict ISO8601
RFC3339 is based on ISO8601 but allows for a few deviations. A notable one is the space to replace the "T" in the UTC DateTime. Instead of providing an entirely separate method, the DateTime to Timestamp exposes a "Strict ISO?" terminal which can be set to false to accept RFC3339 format as a valid date-time string.
Only the "string to timestamp" is implemented at the moment, as a non-strict ISO8601 validation. Pending requests, the Timestamp to RFC3339 formatting could be added easily.
