Why Aren't Java.util.concurrent.timeunit Types Greater Than Seconds Available In Android?

I miss MINUTES, HOURS, DAYS, which exist in documentaion since API level 1 (I use 7th or 2.1 version for the application). I have read this question, where this miss was also poin

Solution 1:

If you open the javadoc for TimeUnit on java 5 and java 6 side by side you will see that these were added in java 6. Android so far only implements java 5.
