Start to time interval curTime when listening to frame event for the second time, obtaining application program launching to the last time listens to frame
Time interval lastTime (application program launching to time interval when listening to frame event for the first time) when event；It will
The difference of curTime and lastTime, be added to it is last update when listening to frame event be locally stored on server time
Server time is locally stored as updated, realizes the update that server time is locally stored.And by curTimer assignment
To lastTime, for next update use.
Since time interval is identical between any two frame, within first update cycle, when listening to frame event for the first time,
The curTime of hypothesis is 0.1s, it is known that, within first update cycle, when listening to frame event for the second time, lastTime is
0.1s, curTime 0.2s.Since within first update cycle, what is updated when listening to frame event for the first time is locally stored
Server time is 10 points 0 0.1 seconds, then when listening to frame event for the second time, and the server time that is locally stored of update is 10 points
0 0.2 seconds.
Since 10 points 0 0.2 seconds intervals of server time are locally stored with updated in 10 o'clock sharp of first server time
Less than predetermined period length, step 102 need to be repeated again and be updated to server time is locally stored, update method institute as above
It states, no longer repeats herein.
When it is updated be locally stored server time be 10 points 0 20 seconds when, 10 o'clock sharp of first server time and update
The interval that server time is 10 points 0 20 seconds that is locally stored afterwards is equal to predetermined period length 20 seconds.Therefore, under can entering
