Key: ORC-346
URL: https://issues.apache.org/jira/browse/ORC-346
Project: ORC
Issue Type: Bug
Components: C++
Reporter: rip.nsk
void TimestampColumnReader::next(ColumnVectorBatch& rowBatch, uint64_t
numValues, char *notNull)
has the following code:
c++\src\ColumnReader.cc:338
int64_t writerTime = secsBuffer[i] + epochOffset;
secsBuffer[i] = writerTimezone.convertToUTC(writerTime);
{color:#f79232}if (secsBuffer[i] < 0 && nanoBuffer[i] != 0) {{color}
{color:#f79232} secsBuffer[i] -= 1;{color}
{color:#f79232} }{color}
{color:#333333}which likely leads to read wrong seconds value for PRE_1970
dates{color}
