strftime() creates memory leak

Hi,

I am facing one strange situation while using strftime() to get current date and time in C.

it leaks memory with %T
Code:
strftime(L_StrDate,30,"%d-%b-%C%y %T", localtime((time_t *)&tv.tv_sec)) ;

and when i use another option then no memory leak like
Code:
strftime(L_StrDate,30,"%d-%b-%C%y  %H:%M%S  -%p",localtime((time_t *)&tv.tv_sec));

my detail code to get time and date is like this -
Code:
char    *GetTimeDate(L_StrFormat,L_NoOfDay)
char    *L_StrFormat    ;
int     L_NoOfDay       ;
{
static  char L_StrDate[31]      ;
static  struct timeval tv       ;

        gettimeofday(&tv,(struct timezone *)NULL)               ;
        tv.tv_sec       = tv.tv_sec + L_NoOfDay*24*3600;
        if (strlen(L_StrFormat) == 0)
        {
                strftime(L_StrDate,30,"%d-%b-%C%y %T",
                localtime((time_t *)&tv.tv_sec))                ;

        }
        else
        {
                strftime(L_StrDate,29,L_StrFormat,
                localtime((time_t *)&tv.tv_sec))                ;
        }
        return(L_StrDate)                                       ;
}

any help will be appreciated.
Thanks
Amit

ovs-parse-leaks(8)						Open vSwitch Manual						ovs-parse-leaks(8)

NAME
ovs-parse-leaks - parses OVS leak checker log files SYNOPSIS
ovs-parse-leaks [binary] < log DESCRIPTION
Many Open vSwitch daemons accept a --check-leaks option that writes information about memory allocation and deallocation to a log file. ovs-parse-leaks parses log files produced by this option and prints a summary of the results. The most interesting part of the output is a list of memory blocks that were allocated but not freed, which Open vSwitch developers can use to find and fix memory leaks. The log file must be supplied on standard input. The binary that produced the output should be supplied as the sole non-option argument. For best results, the binary should have debug symbols. OPTIONS
--help Prints a usage message and exits. BUGS
The output can be hard to interpret, especially for a daemon that does not exit in normal operation. Using ovs-appctl(8) to invoke the exit command that some Open vSwitch daemons support sometimes helps with this. ovs-parse-leaks usually incorrectly reports one or more ``bad frees of not-allocated address'' errors at the beginning of output. These reflect frees of data that were allocated before the leak checker was turned on during program initialization. Open vSwitch August 2010 ovs-parse-leaks(8)
