Try this one:
Code:
$ cat timestamp
#! /usr/bin/ksh

echo enter first time stamp
read TIME1
echo enter second time stamp
read TIME2
H1=${TIME1%:+([0-9])}
M1=${TIME1#+([0-9]):}
H2=${TIME2%:+([0-9])}
M2=${TIME2#+([0-9]):}
H1=${H1#0}
M1=${M1#0}
H2=${H2#0}
M2=${M2#0}
((MAM1=H1*60+M1))
((MAM2=H2*60+M2))
((MAM1>MAM2)) && ((MAM2=MAM2+1440))
((diff=MAM2-MAM1))
echo diff = $diff

exit 0
$ ./timestamp
enter first time stamp
17:30
enter second time stamp
18:05
diff = 35
$ ./timestamp
enter first time stamp
23:59
enter second time stamp
00:01
diff = 2

NAME

       pcap_set_tstamp_type - set the time stamp type to be used by a capture device

SYNOPSIS

       #include <pcap/pcap.h>

       int pcap_set_tstamp_type(pcap_t *p, int tstamp_type);

DESCRIPTION

       pcap_set_tstamp_type()  sets  the  the  type  of  time  stamp  desired for packets captured on the pcap descriptor to the type specified by
       tstamp_type.  It must be called on a pcap descriptor created  by  pcap_create()	that  has  not	yet  been  activated  by  pcap_activate().
       pcap_list_tstamp_types()  will  give  a list of the time stamp types supported by a given capture device.  See pcap-tstamp(7) for a list of
       all the time stamp types.

RETURN VALUE

       pcap_set_tstamp_type() returns 0 on success if the specified time stamp type is expected to be supported by the capture device,	PCAP_WARN-
       ING_TSTAMP_TYPE_NOTSUP  on  success if the specified time stamp type is not supported by the capture device, PCAP_ERROR_ACTIVATED if called
       on a capture handle that has been activated, and PCAP_ERROR_CANTSET_TSTAMP_TYPE if the capture device  doesn't  support	setting  the  time
       stamp type.
