the second object 39 s clock step 302 are compared in step 303 if the times do not match e g the clock of object o 2 is behind the clock of object o 1 the object o 1 may stop step 304 its clock and wait step 305 until the clock of object o 1 is synchronized with the clock of object o 2 the requested object o 2 may continue its operation normally while the requesting object o 1 waits after the clocks are synchronized they may proceed e g at the same speed step 306 the clock speed alignment step 306 is optional however now the object o 1 informs object o 2 about the completed synchronization step 307 and object o 2 returns step 205 shown in fig2 the requested attribute value to object o 1 the read request of object o 1 is now complete step 206 in scenario 220 of fig2 b the clock of object o 2 is ahead of the clock of object o 1 according to the example shown the clock of object o 1 shown with reference number 222 is at a level t 5 whereas the clock of object o 2 is at a level t 8 now there is no need for clock synchronization therefore the read request 223 occurred at the level t.
