time_zone of ISO-IMAGES time_stamps

2025_jun_09_mon 17.17.--.utc

howdy , all ---

i hope that every_one is well ; we are just fine , thank you .



since the early 4s , i have been buying pressed dvds from freebsd_mall .
thus , i have a complete set , from there , through 13.3 and 14.2
   [ i386 , then amd64 ; cd , then dvd ] .

for some reason [ i will inquire , separately ] ,
   13.4 and 13.5 never arrived [ typically , ~ 4 weeks after release ] .
[ no , i was not charged for these ; so , no problem there . ]

in anticipation of replacing , finally , a 11.4 box , w/ 13.5
   [ of course , there are other boxen , w/ later releases ,
       but , none have the last of the 13s ] ,
   earlier today , i down_loaded the 13.4 and 13.5 iso and sum files .

by way of example , please consider this page :
   "https://download.freebsd.org/releases/ISO-IMAGES/13.5/" .

it is nice to see that each of the files has an associated time_stamp ,
   but , there is no indication of the applicable time_zone .

it would be easy to assume that these are all "utc" , --but-- ,
   we all know about the inherent danger in making an assumption .



question_a :
   do all of the various time_stamps use the same zone or
     can the zone vary ?

question_b :
   if consistent , which zone is in force ?

question_c [ clean ] :
   if consistent , could the applicable zone be specified ,
     in the top_of_page header ?

question_d [ messy ] :
   if variable , could the zone be specified w/ the stamp ?



i realize that , because of the global nature of the fbsd project ,
   these time_stamps are , in all probability , consistently "utc" .
none_the_less , i have learned that it is better to ask ,
   rather than to assume .



i extend my best to each of you and to your respective yours .

tia ,
