PDFUnit is able to compare dates (creation and modification dates) as year-month-day or additionally hour-minute-second. Two constants are available to choose between these options:

// Constants for date resolutions:

com.pdfunit.Constants.AS_DATE
com.pdfunit.Constants.AS_DATETIME

You can set a date resolution in the following methods:

// Date resolution in test methods:

.hasCreationDate().after(expectedDate, DateResolution)
.hasCreationDate().before(expectedDate, DateResolution)
.hasCreationDate().equalsTo(expectedDate, DateResolution)

.hasModificationDate().after(expectedDate, DateResolution)
.hasModificationDate().before(expectedDate, DateResolution)
.hasModificationDate().equalsTo(expectedDate, DateResolution)

// Internal used resolution DATE:
.hasSignatureField(..).signedOn(signingDate)

// Comparing two PDF documents, using DATE:
.haveSameCreationDate()
.haveSameModificationDate()

When comparing two PDF documents, date values are always compared using DateResolution.DATE.
