Networkdays with holiday - start date falls on a holiday

Data: Start date and time in col F, end date and time in col L, lead time (hh:mm:ss) in col M. Lead time calculation formula:=IF(ISBLANK(L2),(NETWORKDAYS(F2,NOW(),Holidays)-1+MOD(NOW(),1)-MOD(F2,1)),(NETWORKDAYS(F2,L2,Holidays)-1+MOD(L2,1)-MOD(F2,1)))
Lead time is calculated as soon as the start date is entered, considering current time (NOW) as end date until actual end date and time are entered.
2nd October is in holiday list.

Issue: For rows with start date as 2nd october, lead time does not give the correct result.
E.g. start date and time = 02-10-2014 13:56:00 and End date and time = 07-10-2014 12:03.
Result should be 60:03:00 but I get 46:07:00

I guess this is because, though 2nd october is considered holiday, start time is calculated from 13:56 and not as 3rd october 00:00

Hope I have clearly laid the case. Any help appreciated.

=NETWORKDAYS(F2,IF(L2="",NOW(),L2),Holidays)+NETWORKDAYS(IF(L2="",NOW(),L2),IF(L2="",NOW(),L2),Holidays)*(MOD(IF(L2="",NOW(),L2),1)-1)-NETWORKDAYS(F2,F2,Holidays)*MOD(F2,1)

this one worked.
