Use of deprecated android.text.format.Time

[LiliWeiSE]

Hi,

I noticed that class android.text.format.Time has been used in multiple places, such as: Line 1371 in ScheduleImportantFragment.java Line 276 and 280 in Schedule.java

This class has been deprecated in API 22 due to multiple problems (see https://developer.android.com/reference/android/text/format/Time.html)

Although it may not cause problems for now, I think it may be better to use other alternatives to avoid future bugs.

Thanks!
