Incremental date-time

I would like to redate a number of files with an incremental date/time

e.g.
FROM:
Modified
21-04-2015 06:55:28
09-05-2015 17:53:58
26-01-2015 18:38:54
09-05-2015 17:47:56
06-06-2013 09:22:06
14-05-2015 09:07:40
09-05-2015 17:50:18
31-01-2012 13:01:40

05-04-2005 08:26:41
05-04-2005 08:27:41
05-04-2005 08:28:41
05-04-2005 08:29:41
05-04-2005 08:30:41

where, in this case, the modified date remained unchanged, time sequence is set to increase by 1 minute.

Or leave the time unchanged and increase the day stamp by xx days (e.g. 1 day)

like:
Modified
28-10-2015 08:24:41
29-10-2015 08:24:41
30-10-2015 08:24:41
31-10-2015 08:24:41
01-11-2015 08:24:41
02-11-2015 08:24:41

Thanks
