found the reason why it happens: https://github.com/FreeOpcUa/opcua-asyncio/blob/f6aa7a972fdc742ff2c983aa1a00437bb359702b/asyncua/server/server.py#L114

https://reference.opcfoundation.org/v104/Core/DataTypes/BuildInfo/

buildDate | UtcTime <-- we propably should make docstrings to hint the types or make some typechecking?

@oroulet if you agree i fix it with a PR?

Fine for me
