QDateTime QuaZipFileInfo64::getNTFSaTime ( int * fineTicks = NULL ) const

The getNTFS*Time() functions only work if there is an NTFS extra field present. Otherwise, they all return invalid null timestamps.

Parameters

fineTicks If not NULL, the fractional part of milliseconds returned there, measured in 100-nanosecond ticks. Will be set to zero if there is no NTFS extra field.

See Also: dateTime; getNTFSmTime(); getNTFScTime()

Returns: The NTFS access time, UTC

QDateTime QuaZipFileInfo64::getNTFScTime ( int * fineTicks = NULL ) const

bool QuaZipFileInfo64::toQuaZipFileInfo ( QuaZipFileInfo & info ) const

If any of the fields are greater than 0xFFFFFFFFu, they are set to 0xFFFFFFFFu exactly, not just truncated. This function should be mainly used for compatibility with the old code expecting QuaZipFileInfo, in the cases when it's impossible or otherwise unadvisable (due to ABI compatibility reasons, for example) to modify that old code to use QuaZipFileInfo64.

Returns: true if all fields converted correctly, false if an overflow occured.

QDateTime QuaZipFileInfo64::dateTime

This is the time stored in the standard ZIP header. This format only allows to store time with 2-second precision, so the seconds will always be even and the milliseconds will always be zero. If you need more precise date and time, you can try to call the getNTFSmTime() function or its siblings, provided that the archive itself contains these NTFS times.
