+config CMD_UT_TIME
+ bool "Unit tests for time functions"
+ help
+ Enables the 'ut_time' command which tests that the time functions
+ work correctly. The test is fairly simple and will not catch all
+ problems. But if you are having problems with udelay() and the like,
+ this is a good place to start.
