While checking in User-Guide.pdf supplied with the latest dev download and searching for details related to kissutil command line parameters the search includes a reference on page 135 in the section discussing command line parameters for direwolf.
Although the syntax for the -T parameter is the same for kissutil as it is for direwolf the reference on page 135
"If you want UTC, rather than local time, set the TZ environment variable before
running kissutil."
should more accurately be
"If you want UTC, rather than local time, set the TZ environment variable before
running direwolf."
