Abstract
There is provided a technique of time delivery in a computing system comprising a system call interface (SCI) located in a kernel space and operatively connected to a time client located in a user space. The technique comprises: using a time agent component located in the user space to measure data indicative of delay in a system time delivery and to derive therefrom a system time delivery error TES2C; using TES2C to enable correction of system time; and sending by the SCI the corrected system time in response to a “Read Clock RT” (RCRT) call received from the time client. The method can further comprise: measuring data indicative of delays in the system time delivery for RCRT calls with different priorities; and in response to a system time request received from the time client, providing the time client with system time corrected per TES2C corresponding to the recognized priority thereof.
