Mismatching of quarterly EPS surprise date and earning announcement dates

fersa375

I'm doing a research on Taiwan market and retrieved earning surprise data from DataStream. for example, I collected quarterly earing surprise announcement dates (EPSISURDTE) and quarterly EPS surprise score (EPSISURSUE),

I find EPSISURDTE is different from quarterly earnings announcement dates on TWSE. What is the EPSISURDTE? Why it is substantially different form earning announcement date? Following table compare two dates for KYG01408106 (code 1590).
