Make it possible to define format for time that is displayed. The way the format is defined is equal to the way that is used for strftime function, although not all formatting options as used in strftime are available for LVM2 - the set is restricted (e.g. we do not allow newline to be printed). The lvm.conf comments contain the whole list that LVM2 accepts for time format together with brief description (copied from strftime man page). For example: (defaults used - the format is the same as used before this patch) $ lvs -o+time vg/lvol0 vg/lvol1 LV VG Attr LSize Time lvol0 vg -wi-a----- 4.00m 2015-06-25 16:18:34 +0200 lvol1 vg -wi-a----- 4.00m 2015-06-29 09:17:11 +0200 (using 'time_format = "@%s"' in lvm.conf - number of seconds since the Epoch) $ lvs -o+time vg/lvol0 vg/lvol1 LV VG Attr LSize Time lvol0 vg -wi-a----- 4.00m @1435241914 lvol1 vg -wi-a----- 4.00m @1435562231
