Although Reno isn't explicitly shown on this map,   all of Nevada is shown to be in the same time zone as all of Washington state, the vast majority of Oregon, and all of California.

There are other maps that show the same boundaries, and, having been to both Reno and Seattle (as well as Oregon and California), I am certain that they are in the same time zone. That time zone is three hours behind official WDC clock time, meaning that when it's midnight here, it's 9pm there. I've double-checked the countdowns, because I've been known to get confused by this sort of thing myself, and they appear to be correct.

(For the sake of pedantry, there are a few border towns in Nevada that observe Mountain Time, but none of them are Reno.)
