Ang 6220 Add API that support direct mode in Clock control.

Based on arguments of setDate(), Clock control can be "normal" mode and "direct" mode.
If it is "direct" mode, then
-The clock's refresh timer should be disabled (it should not automatically tick forward)
-The clock's date formats should be reinitialized to use timezone:"Etc/UTC"
-The clock should be refreshed using the time components in the object given by creating a new iLib date directly from these components using timezone:"Etc/UTC", to ensure that no timezone conversion/validation is used.
