asset_wire = AssetWire.model_validate({
    "symbol": "AAPL",
    "currency": "USD",
    "validFrom": 1609459200000  # Unix timestamp in ms
})

# Convert to runtime format
asset = Asset.from_wire(asset_wire)
print(asset.valid_from)  # datetime object

# Convert back to wire format
wire_data = asset.to_wire()
json_str = wire_data.model_dump_json(by_alias=True)
