Strange permission requirements invalidate the wmic command, so when adjusting the time, user need to specify the time format for their region, default command is '[time ]HH[:]mm[:]ss[.]SS[ && date ]MM[-]DD[-]YY', which means 'time HH:mm:ss.SS && date MM-DD-YY'
Bug fixed:
Using keep-alive to Get more accurate calculations;
--user-agent default to none;
Adjust time using fixed UTC format in shell commands;
Code error in the version display;
New:
http2 protocol;
Option --verbose make the operation more talkative;
