Detailed Description

UA_DateTime wrapper class.

An instance in time. A DateTime value is encoded as a 64-bit signed integer which represents the number of 100 nanosecond intervals since January 1, 1601 (UTC).

See also: https://reference.opcfoundation.org/Core/Part6/v105/docs/5.2.2.5

Examples: client_connect.cpp, client_minimal.cpp, client_subscription.cpp, events/client_eventfilter.cpp, and server_valuecallback.cpp.
