Bug 5653 - Display "Day of Year" for January 1 as 1, not 0

[Matthew Parris <parrisimo () gmail com>]

I'd like some others to comment regarding this proposed change.  See Bug
5653 <https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=5653>.


> In to_str.c, the abs_time_to_str and abs_time_secs_to_str functions creates a
> string for display using gmtime.  This patch affects those using the
> "ABSOLUTE_TIME_DOY_UTC" conversion case.
>
> The tm_yday "Day of Year" parameter is defined by gmtime as "The number of days
> since January 1, in the range 0 to 365"  so the tm_yday parameter equals zero
> for January 1.  Similarly, the tm_year "Year" is defined as "The number of
> years since 1900" so the tm_year parameter equals zero for 1900.
>
> Within the abs_time_to_str function, 1900 is added to the tm_year parameter,
> but 1 is not added to the tm_yday.  I'm used to seeing the day of the year
> equal to 1 on January 1st.  Does anyone use 0 for January 1?
