Figure 11.1, from Giga Information Group, shows the relationship of the RTC and the BIOS and what happens with century indicators in Y2K compliant and non-compliant PCs.įor the most part, the PC operating systems that are widely used in business are or can be made Y2K ready. Since the BIOS and RTC are closely intertwined, they are frequently referenced using the compound term RTC/BIOS or BIOS/RTC. About 4% get it from the BIOS itself, and only 1% or so of PC applications go directly to the PC's RTC for the system date and time.

Norbert Kriebel, an analyst at the Giga Information Group, estimates that 95% of the applications in the DOS, Windows 3.x, Windows 9x, and OS/2 environments get their time/date from the OS. There are exceptions and variations to how a PC application gets its date information, but most follow the flow described above. Or enter the Excel spreadsheet function =TODAY() in a cell, hit Enter, and today's date, including the proper century indicator if you have Excel set to display four-digit years, will appear in the cell. Type and send an email message, and your email application automatically stamps it with the time and date. The OS, in turn, sends the date to your favorite applications. When you turn on your PC, the BIOS checks with the RTC for the time/date and passes it to the operating system. So even after you have turned off your PC for the day, an incremental counter in the RTC continues to count off the minutes and seconds to maintain the time and date you originally set. The time and date stored in the RTC are kept alive by a small battery. You can also set the time and date by entering your PC's setup mode, usually by pressing a Function key just before your operating system kicks in. The latter stores and maintains the system time and date in the PC's CMOS (complimentary metal oxide semiconductor). This information is passed to the BIOS (basic in/out system), an application that resides permanently in ROM (read only memory), which in turn sets the PC's RTC (real time clock).

If you have ever had occasion to install an operating system Windows 98, for example you will recall that during installation, you were prompted to enter your time zone and set the time and date. Much like the date glitches in mainframes, non-compliant hardware, operating systems, or applications may lose track of time beyond year 2000. You will find these must-have business appliances on office desktops, in home offices, in bedrooms, and you will even see perfectly sane people hammering away on notebook PCs on airplanes and at poolside.Īre PCs - I am talking about the IBM compatibles that hit the market in the early-1980s - vulnerable to Y2K problems? You bet. In all sorts of businesses, big and small, when people think of computers, they think of PCs.
