- // Encodes a timer containing a timestamp and a user specified payload.
- // The encoding is represented as: timestamp payload
- // timestamp - a big endian 8 byte integer representing
millis-since-epoch.
- // The encoded representation is shifted so that the byte
representation of
- // negative values are lexicographically ordered before the byte
representation
- // of positive values. This is typically done by subtracting

- // from the value and encoding it as a signed big endian integer.
Example values:
+ // Encodes a timer containing a user key, a clear bit,
+ // a fire timestamp, a hold timestamp, the windows that the user key is in,
+ // the paneinfo of the user key.
+ // The encoding is represented as:
+ // user key - user defined key, uses the component coder.

Review comment:
The *dynamic tag* is supposed to be part of the encoding.
