Timezones in a part of Kazakhstan (Asia/Qyzylorda changed its offset and
new timezone Asia/Qostanay was added), a part of Alaska, São Tomé and
Príncipe changed at the end of 2018 or at the beginning of 2019. They
require this update now.

Either in JS console in Chrome or v8 should work like these:
d8> new Date(Date.UTC(2018,11,20,12)).toLocaleString("en", {timeZone: "Asia/Qyzylorda"})
"12/20/2018, 6:00:00 PM"
d8> new Date(Date.UTC(2018,11,21,12)).toLocaleString("en", {timeZone: "Asia/Qyzylorda"})
"12/21/2018, 5:00:00 PM"
d8> new Date(Date.UTC(2018,11,20,12)).toLocaleString("en", {timeZone: "Asia/Qostanay"})
"12/20/2018, 6:00:00 PM"
d8> new Date(Date.UTC(2018,11,21,12)).toLocaleString("en", {timeZone: "Asia/Qostanay"})
"12/21/2018, 6:00:00 PM"
d8> new Date(Date.UTC(2018,11,31,12)).toLocaleString("en", {timeZone: "Africa/Sao_Tome"})
"12/31/2018, 1:00:00 PM"
d8> new Date(Date.UTC(2019,0,1,12)).toLocaleString("en", {timeZone: "Africa/Sao_Tome"})
"1/1/2019, 12:00:00 PM"

Future expected changes in Iran and Moroco are also included in this update.
