How to use the zeroTime in token bucket?

[zhang s]

When i use the constructor of token bucket,  i find the parameter zeroTime seems not work.

How can i use it correctly？

By default token bucket is "full" after construction, but i don't want this.I want the token bucket is "empty" after construction.

code:

// generate one token per second, burst size is 10.0 but bucket size is empty after initialization

folly::TokenBucket token_bucket(1.0, 10.0);

Sorry for my poor english.
