Checking next alarm time

The following code checks the time point of next alarm and calculates the corresponding time duration until the alarm occurs.

    private AlarmInfo CheckForNextAlarm(Context context) {

        AlarmInfo alarmInfo = new AlarmInfo("","");

        try {
            // First check for regular alarm
            AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
            if (alarmManager!=null)
            {
                AlarmManager.AlarmClockInfo clockInfo = alarmManager.getNextAlarmClock();
                if (clockInfo!=null)
                {
                    long nextAlarmTime = clockInfo.getTriggerTime();
                    Date nextAlarmDate = new Date(nextAlarmTime);
                    android.text.format.DateFormat df = new android.text.format.DateFormat();

                    // Format alarm time as e.g. "Di. 06:30"
                    alarmInfo.alarmTime = df.format("EEE HH:mm", nextAlarmDate).toString();

                    Date dateNow = new Date();
                    long diffMilliSec = nextAlarmDate.getTime() - dateNow.getTime();
                    long seconds = diffMilliSec / 1000;
                    long minutes = seconds / 60;
                    long hours = minutes / 60;
                    // long days = hours / 24;

                    if (hours > 0)
                    {
                        alarmInfo.durationUntilAlarm += hours + " h";
                        minutes -= (hours*60);
                    }
                    if ((hours > 0) && (hours <= 99))
                    {
                        // display both hours and minutes
                        alarmInfo.durationUntilAlarm += " ";
                    }
                    if (hours <= 99)
                    {
                        alarmInfo.durationUntilAlarm += minutes + " m";
                    }
                }
            }

            // If regular alarm is not set check for alarm possibly set
            // by other applications
            if (alarmInfo.alarmTime.isEmpty())
            {
                alarmInfo.alarmTime = "" + Settings.System.getString(context.getContentResolver(),
                        Settings.System.NEXT_ALARM_FORMATTED);
            }
        } catch (Exception e) {
            // Possible extension: write e.getMessage() to some log file
        }
        return alarmInfo;
    }
