Yotta login or install gets errors

Hi all,

recent days I install yotta to another PC(win7), when I want to login my account in yotta, it gets an error message,
or I try to add a k64f target, it shows the error too.

then I try to find out the solution to these issue, and there is the same issue in the linux,
https://github.com/ARMmbed/yotta/issues/669
the solution in linux is sync the system time then the issue just solved, but I try to use the same way to solve the issue in win7, it looks like no use.

so, has there some new solution to solve this issue?

The solution is: modify the system time manually(without sync), then the function would be work.
