Calculate difference in time (between current and next day)

There is a lot of similar topics but I couldn't find something similar then my problem. I've found only how to calculate if for example second time is greater then first time, like:

  1. 22:00
  2. 23:00

The result is easy to get. Just subtract second time with first using Date API. Difference is in milliseconds and you can easily convert them in seconds/minutes..

What I want to know, how to get difference between time in first day and time in second day, for example:

  1. 22:25
  2. 06:30

Difference should be 8 hours and 5 minutes.

Or another example

  1. 19:00
  2. 00:00

Difference should be 5 hours.

How to calculate time in this way? Any help is appreciated.

Use Calendar class. Set your day, hour and minutes and finally subtract those dates (in milliseconds) and you will convert result in hour, minutes and seconds.

Convert your date and time to TimeStamp (It's just the long representation of a date in milliseconds since Jan. 1, 1970.), then calculate difference, and transferred from milliseconds to hours.
