Hi,

If you read the warnings you will see what is wrong:

  packet-xxx.c(1077) : warning C4244: '=' : conversion from 'time_t'
to 'unsigned int', possible loss of data

This warning tells you that you are trying to convert a time_t to an
unsigned int, which may lead to loss of data.  In Wireshark
nstime_t.secs is defined as time_t, not unsigned int.

You can fix this in one of two ways:

1. Use correct data types for hours, mins and secs:
time_t hours;
time_t mins;
time_t secs;

2. Add a cast in the assignment:
hours = (unsigned int)(tagv.secs / 3600);
mins = (unsigned int)((tagv.secs - (hours * 3600)) / 60);
secs = (unsigned int)(tagv.secs - (hours * 3600) - (mins * 60));
