Constructor Details

#initialize(seconds_item_name, microseconds_item_name = nil) ⇒ UnixTimeSecondsConversion

Initializes converted_type to :FLOAT and converted_bit_size to 64

Parameters:

  • seconds_item_name (String) —

    The telemetry item in the packet which represents the number of seconds since the UNIX time epoch

  • microseconds_item_name (String) (defaults to: nil) —

    The telemetry item in the packet which represents microseconds

Instance Method Details

#call(value, packet, buffer) ⇒ Float

Returns Packet time in seconds since UNIX epoch.

Parameters:

  • value (Object) —

    The value to convert

  • packet (Packet) —

    The packet which contains the value. This can be useful to reach into the packet and use other values in the conversion.

  • buffer (String) —

    The packet buffer

Returns:

  • (Float) —

    Packet time in seconds since UNIX epoch
