Please rewrite it :) Stef On Apr 14, 2013, at 9:52 PM, Igor Stasenko <siguctua@gmail.com> wrote:

the more i learn about DateAndTime the more i lean towards completely rewriting this ... err.. crap. (yes. sorry for harsh word).

DateAndTime class>>now is not thread-safe..

now | nanoTicks msm |

nanoTicks := (msm := self milliSecondsSinceMidnight) * 1000000.

(LastTick < nanoTicks) ifTrue: [ LastTick := nanoTicks. ^ self todayAtMilliSeconds: msm].

LastTickSemaphore critical: [ LastTick := LastTick + 1. ^ self todayAtNanoSeconds: LastTick]

Wrapping only single assignment to variable with critical section while leaving another without it is same as if not using critical section at all.
