title: What does LSN mean in SQL Server?
body: <p>What is the meaning of Log Sequence Number? I know that it is of type binary and 10bytes long and it corresponds to the time the transaction happen in DB. But is this a high precision date-time value that is stored in some efficient binary format or is this a function of date-time and something else (for example the serial number of transactions that happen at the same milli second). I did a lot of searching but couldn't find a good answer to this.</p>
  
  <p>Can any one explain with a formula or function that is used to derive the LSN from date-time or anything.</p>
