* This file contains routines to generate a change sequence number. Every
* add delete, and modification is given a unique identifier for use in
* resolving conflicts during replication operations.
*
* These routines are based upon draft-ietf-ldup-model-03.txt, and will
* need to be revisited once standardized.
*
* The format of a CSN string is: yyyymmddhh:mm:ssz#0xSSSS#d#0xssss
* where SSSS is a counter of operations within a timeslice, d is an
* offset into a list of replica records, and ssss is a counter of
* modifications within this operation.
*
* Calls to this routine MUST be serialized with other calls
* to gmtime().
