In addition, we believe that we have addressed all of the following comments
from the first contribution:
>Quick review:
>We've been Wireshark for some time now. Please don't roll back to the Ethereal
>days.
>We no longer depend on our own snprintf, so don't try to include that.
>What's wrong with using GLib or libc provided time conversion functions?
>proto_register_ccsds() is not the place to setup value_string's, this is
>normally done at module level.
>value_string's are never directly included in header fields, they are to be
>wrapped in VALS() macro.
>Header fields with type FT_BOOLEAN use the 'display' field to set the width of
>the parent bitfield (ref. README.developer). Do not change such sizes into
>BASE_* values.
>If header field 'names and 'blurb' fields are the same, fill 'blurb' with NULL.
However, one issue the time format.
It was requested in the previous comment to use the GlibC functions to format
the time. However none of the glibc functions can format the time in precisely
the manner that we use for these protocols, so we format it in the software,
simply to conform to the HOSC standard.
For those interested, documentation of these protocols can be found at:

However it is required to create a UserID and password. Questions or comments
