On either Unix (FM7) or Win7 (FM9), the string looks like:
username/Real Name/sysname/Mon Jul 28 07:43:27 2014/1406551407/1/
username/
Login name of user holding lock
/Real Name/
Full name of that user
/sysname/
System (PC, workstation, or VM instance I suppose) name
/Mon Jul 28 07:43:27 2014/
Time of most recent Write (apparently not time of Open)
/1406551407/
Might be same timestamp, as Unix Epoch (seconds since 00:00:00 1970-01-01 UTC).
Might also be some other time, such as Open. The Solaris system I'm using lacks a manpage for the various date and clock commands, and isn't responding to standard options, so I wasn't able to decode it. The readable date and the 14.... are real instance. If they match, it's Write date. If the 14... stamp is earlier by minutes, it's Open.
/1/
Beats me, but was "1" on both systems.
