Abstract:
1. A system for reconfiguring a real time clock time of a computer, the system being stored in a basic input/output system (BIOS) that is connected with a complementary metal-oxide-semiconductor transistor random access memory (CMOS RAM), the system comprising: a storing module for storing an initial real time clock (RTC) time from the CMOS RAM into the BIOS when the computer is powered on; a calculating module for calculating a first elapsed time tracked from the initial RTC time and a second elapsed time tracked from the initial RTC time; a reading module for reading a first RTC time of the computer after a first time span of the first elapsed time; a detecting module for detecting whether the first RTC time equals the sum of the initial RTC time and the first elapsed time for determining whether the first RTC time has errors; and an adjusting module for adjusting a second RTC time of the computer after a second time span of the second elapsed time to the sum of the initial RTC time and the second elapsed time, upon the condition that the first RTC time has errors and a time recovery request is received.
