Given two date strings d1 and d2 of the form yyyy/mm/dd HH:MM:SS (assume hours HH is in 24 hour mode), determine how much time, in decimal hours, separates them. Assume d2 is always later than d1.

Example:

 Input d1 = '2010/12/14 12:00:00'
 Input d2 = '2010/12/14 13:06:36'
 Output elapsed is 1.11

with an existing funcion it is solveable

Bugrahan Atar on 9 Feb 2021

function elapsed= elapsed_time(d1,d2)
d1='2010/12/14 12:00:00'
d2='2010/12/15 13:06:36'
a=(str2num(d2(1:4))-str2num(d1(1:4)))*8760;
b=(str2num(d2(6:7))-str2num(d1(6:7)))*720;
c=(str2num(d2(9:10))-str2num(d1(9:10)))*24;
e=str2num(d2(12:13))-str2num(d1(12:13));
f=(str2num(d2(15:16))-str2num(d1(15:16)))/60;
g=(str2num(d2(18:19))-str2num(d1(18:19)))/3600;
elapsed=a+b+c+e+f+g
end

it told me that solution is wrong?
