33 * 2019/06/17 Redesign to ZonedDateTime because of sync problems.
35 * Function is handling the NETCONF and the format used by database and restconf communication.
37 * Input supported for the formats used in NETCONF messages:
39 * Format1 ISO 8601 2017-01-18T11:44:49.482-05:00
41 * Format2 NETCONF - pattern from ietf-yang-types "2013-07-15" Pattern:
