I'm not sure if this can be done as it ties into the lock screen, but;

When receiving a call, you cannot view the time of day anywhere on the device until you answer or ignore the call. You can see the date at the top. Check it out.

Since I have call forwarding set up from work often, it would be nice to see the time of day because then I would know to let it go to voicemail instead of answer after hours.

Just an idea for a patch if possible, if interested.
