[Bug-ddrescue] Not really a bug about timestamp, but rather a suggestion

[Rikard Bosnjakovic]

I recently upgraded from ddrescue 1.16 to 1.20 and noticed that there 
are two timestamps (start / current) in the logfile. This is good info.

However, I have a suggestion for this. As for now, the start time seems 
to be changed everytime ddrescue is invoked for the particular logfile. 
This has shown to be a bit pointless for some of the drives I've run 
ddrescue on, which I have to kill ddrescue and reset the drive to be 
able to continue (somehow the kernel just dropped it and reset was the 
only way out). But resetting the drive and program also resets the start 
time, which is a bit weird.

My suggestion is this: only write the start time once, when the logfile 
is created. Concurrent runs only updates the current time, as it does 
now. Perhaps adding another field: "Number of runs", or similar?

This is an except for a very damaged drive I worked with last week, and 
had to reset the drive for atleast 40 times before finally being able to 
work on the rescued image:

# Start time:   2015-11-02 09:11:28
# Current time: 2015-11-02 09:12:00

That info is surely hiding what actually happened :-)


Just my two cents.
