Step 282: the poor Δ t that calculates corresponding adjacent R TC system time t;
Step 283: every the Δ t time, just add mean value on this RTC system time
proofread and correct once;
Wherein, because the standard time data of obtaining can not be complete precise time data, the in the situation that of long-time suspension, predicated error may become and makes greatly correction time accurate relatively not, is therefore recovering after network, can solve this problem by upgrading standard time data.
Step 290: according to current standard time renewal RTC system time, and preserve current standard time data;
