rem ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
rem -----------------------------------------
rem Boolean settings below, use the following values to enable/disable behavior:
rem to Enable, set to: true
rem to Disable, set to: false [or undefined]
rem -----------------------------------------
rem Note: When below setting is undefined/false, output is seconds; otherwise, when value is 'true', output is in milliseconds
set "utx_out_ms=false" rem Default: ; Description: utx_out_ms --- will display with ms upto 1000 ms
rem -----------------------------------------
rem Note: UTC timezone/DST/offset source binary; when both are false, script will not use either; when both true, uses wmic only
set "utx_tz_w32tm=false" rem Default: false; Description: utx_tz_w32tm --- will use the w32tm.exe to get timezone info
set "utx_tz_wmic=true" rem Default: true ; Description: utx_tz_wmic --- will use the wmic.exe to get timezone info
rem -----------------------------------------
rem ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
rem ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
rem -----------------------------------------
rem String settings below, use expected strings
rem to Enable, set to: <string>
rem to Disable, set to: [undefined]
rem -----------------------------------------
rem The following is to bypass asking the w32tm.exe/wmic for the timezone settings. Value should be in seconds (integer). When value is undefined, script will ask the OS for timezone configuration.
rem -- Example: UTC+7 hours (aka 420 min), value would be: 25200
rem -- Example: UTC+0 hours (aka 0 min), value would be: 0
rem -- Example: UTC-10 hours (aka 600 min), value would be: -36000
