Is this a bug?

When I schedule a job via the Immediate Window using this command. . .
System.schedule('Batch Update Contacts (Daily at 2:00 PM)', '0 0 14 * * ?', new ScheduleBatchUpdate_Contacts());

. . . this is what shows up in Setup | Monitoring | Scheduled Jobs:

The UI has it wrong: this job will run every day, NOT just on the first of each month.

I was surprised I didn't find any hits on the intarwubs. I'm posting to StackExchange and see if anyone has insight.

In the meantime, I'd say:
a job that can be scheduled via the UI should be scheduled via the UI, not the Immediate Window.  
any job that runs once-daily or less should be scheduled via the UI.

Yup, it's a bug. 

Using the string below runs the same schedule from the Immediate Window. . .
System.schedule('Batch Update Contacts (Daily at 2:00 PM)', '0 0 14 ? * Sun,Mon,Tue,Wed,Thu,Fri,Sat', new ScheduleBatchUpdate_Contacts());

. . . and shows up correctly in the UI:
