Get the previous (old) time after changing the time

Question

I can receive time change events using translation events ( ACTION_TIME_CHANGEDand ACTION_DATE_CHANGED).

I need to get the previous time after changing the time . For example, the current time is 10:00. I am going to change the time until 12:00. After changing the time, the time will be changed to 12:00, but I need to get the previous time (10:00) during the time change.

Note. The time can be changed from any other application or from the settings.
