Duration calculation
Loadshedding counting start after 30 seconds of AC_Fail
Normally it count the duration of Loadshedding upto 240 minutes or 4 hours. After 240 minutes it add 1 per 60 minutes.
so Duration 241=240+60 minutes.
or Duration 245=240minute +5hours
This technique is continue upto 250 count. after 250 it add 1 for per 1 day.
so Duration 251=240minute +10hours+1day

This compressed duration is used in only loadshedding history or into data log. Because each memory cell size are limited upto 255. But Total loadshedding will show in actual total minutes.
