How to do calculation on time values imported from Excel?

Viewed 57

I have the following values in Excel:

  • Bed time 19:34:00
  • Get up time 07:04:00
  • Time in bed 11:30:00
  • Sleep start 19:42:00
  • Sleep end 07:00:00

I want to import them into MATLAB and do some calculation on these time values such as subtraction. The time values look like this after importing:

  • 0.8153
  • 0.2944
  • 0.4792
  • 0.8208
  • 0.2917

and obviously doing calculation on them would be nonsense. Would any body help me with this issue? I have stuck with it for few days, and no progress yet.

Thanks in advance,
