Ssc cgl date of birth discrepancy

I have appeared for SSC CGL 2018 and secured AIR 35. I have an issue as my Document Verification is pending. If successful will be joining as Inspector(Examiner) In Customs. 1>My Matric Certificate and Photo IDs have Date of Birth mentioned as 13th Feb,1993 whereas my Birth Certificate (issued by Kolkata Municipal Corporation)has recorded date as 13th May,1993 .(eligible for all SSC CGL posts as per both Date of Births-age 27 years approx as per both certiifcates) 2)Mistakenly, I assumed Birth Certificate is the final age proof and hence have entered 13/05/1993 (as per Birth Certificate)in SSC CGL 2018 application form instead of 13/02/1993(as per Matriculation Certificate) but later discovered that SSC accepts Matric Date Of birth as final proof.of age. 3)The discrepancy can be a problem became evident to me when a notice was issued during Tier 2 to carry additional age proof as per application form in case of mismatch and I carried my Birth Certificate along with me to exam centre. 4)During Registration in SSC portal for CGL 2018 I have mentioned my Matric Certificate number (which has the Date of Birth mentioned as well as my picture) correctly,which is also a proof of the fact that the error was unintentional and I had no intention to hide any information.) As the commission has various processes like Photos captured during all tiers of the examination,fingerprints,signature,handwriting,biometrics,will I be allowed during Document Verification or my candidature will be rejected?
