Deceptive comment in wfdb2mat output
wfdb2mat adds info strings along the lines of
#Creator: wfdb2mat
#Source: record 12063/ Start: [11:04:21.104]
The "start time", however, is deceptive: it's actually just the base time of the output record, as returned by mstimstr(0). (This, of course, makes no sense: the base time is recorded at the start of the header file, there's no need to put it in an info string.)
What would make sense - and what I'm sure was the original intention - would be for the comment to record the starting time relative to the original input record (i.e., the "-f" argument to wfdb2mat.) This is not equivalent to the base time of the new record if there is no base time, or if there's no base date and the new record begins after the first day of the original record.
