Late binding is using System.object instead of explicitly declaring a class (which is early binding).

I worked overtime for 3 hours.

 It depends on whether it REALLY matters or not. Now days it seems like 8am-5pm is completely stupid unless you are working a job like in a call center or something like that. If the person is getting their work done and not adversely affecting other employees, why should you care anyway?

Extended Binary Coded Decimal Interchange Code (EBCDIC) is an 8-bit character encoding (code page) used on IBM mainframe operating systems such as z/OS, OS/390, VM and VSE, as well as IBM minicomputer operating systems such as OS/400 and i5/OS (see also Binary Coded Decimal). It is also employed on various non-IBM platforms such as Fujitsu-Siemens' BS2000/OSD, HP MPE/iX, and Unisys MCP. It descended from punched cards and the corresponding six bit binary-coded decimal code that most of IBM's computer peripherals of the late 1950s and early 1960s used.
