Mac upgrade ssd

mac upgrade ssd
My macbook pro is 2011 early 13' one. Recently I update 256G ssd disk to it. When use usb reinstall Yosemite (https://support.apple.com/en-us/HT201372), I meet an error "This copy of the Install OS X Yosemite application can’t be verified. It may have been corrupted or tampered with during downloading." After some googling, the reason is system date is 2001, change it current date (2015), then install success. date 0920173316
