Guy I just confirmed that this is UTC time. Sorry for the confusion. Thanks, Brian Guy Harris wrote:

The function to get the value would be tvb_get_ntoh64(), but that just gives you a guint64 count of milliseconds. If you want to add that to the protocol tree as an FT_ABSOLUTE_TIME, that requires more work. First - is that midnight, January 1, 1970, UTC, or midnight, January 1, 1970 *local* time? If it's local time, that's a bit more work; I'll assume it's UTC here. Values for FT_ABSOLUTE_TIME fields are nstime_t's; those are structures with a "secs" and "nsecs" field. If you have a 64-bit milliseconds since the Epoch, and you want to convert it to an nstime_t for use with an FT_ABSOLUTE_TIME field, you'd do guint64 msecs_since_the_epoch; nstime_t t; ... t.secs = msecs_since_the_epoch/1000; t.nsecs = (msecs_since_the_epoch%1000)*1000000; /* milliseconds to nanoseconds */ ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe
