Subject: [PATCH] ID:437 - sel: Fix "sel time set <time>"

Presently 'sel time set' doesn't account 'minute' difference between timezone.
So depending on host timezone it may set time to +/-30 mins. This patch adds
minute difference to delta_hour caluclation so that it sets time properly.

output without patch:
  # ./ipmitool sel time get
  03/24/2016 12:34:03
  # ./ipmitool sel time set "03/24/2016 12:34:03"
  03/24/2016 12:04:03
  # ./ipmitool sel time get
  03/24/2016 12:06:09

output with patch:

  # ./ipmitool sel time get
  03/30/2016 08:49:47
  # ./ipmitool sel time set "03/30/2016 08:09:47"
  03/30/2016 08:09:47
  # ./ipmitool sel get
  03/30/2016 08:09:57
