This example shows how to add or substract minutes in current time
using Java Calendar class.

//create Calendar instance
Calendar now = Calendar.getInstance();
System.out.println("Current time : " + now.get(Calendar.HOUR_OF_DAY)

//add minutes to current date using Calendar.add method
now.add(Calendar.MINUTE,20);
System.out.println("New time after adding 20 minutes : " + now.get(Calendar.HOUR_OF_DAY)

+ now.get(Calendar.SECOND));
/*
* Java Calendar class automatically adjust the date or hour accordingly if adding
* minutes to the current time causes current hour or date to be changed.

//substract minutes from current date using Calendar.add method

+ ":"
+ now.get(Calendar.MINUTE)
+ ":"
+ now.get(Calendar.SECOND));

/*
Typical output would be
Current time : 16:34:11
New time after adding 20 minutes : 16:54:11
Time before 25 minutes : 15:44:11
