Haha, I'd be happy if VTA paid more attention to the time their platforms display. The time on at least half the platforms is off by 3 to 4 minutes from my phone's time (which is set on automatic).
Forget that, when DST stopped in November, the large VTA digital clocks were displaying PDT instead of PST for ONE WHOLE WEEK, and I'm talking about a major station in downtown San Jose.
So yeah, catching the train is basically a guessing game.
