    Hi,

    I am porting a kernel module in AIX 5.3. To performing timestamping within this module

    (a) Is there a kernel based gettimeofday() or equivalent to obtain time from the designated epoch ? I went through the kernel symobls and did not see anything similar to gettimeofday()

    (b) Are there kernel variables indicating the time zone ?

    Thanks,

    Sri

    Hi,
    Please check this site for time-service in AIX kernel:
    http://publib.boulder.ibm.com/infocenter/systems/index.jsp?topic=/com.ibm.aix.kerneltechref/doc/ktechrf1/curtime.htm

    Also, I am interested to know why do you need time in kernel mode.

    Please note that this forum is rarely answered. It is a pity that no one from IBM bothers to check-it and respond.
    I always like to discuss AIX kernel with other developers. If you are interested, please let me know.

    Thanks,
    Eran.
