' The MinDate and MaxDate properties use the timestamp date/time string format.
' Here are some examples:
' YYYY-MM-DD (e.g., 2024-07-31)
' YYYY-MM-DDTHH:MM:SS�HH:MM (e.g., 2024-07-31T12:34:56+02:00)
' 2024-07-31T12:34:56Z (the "Z" denotes Zulu time, or UTC)

' Only unzip files having a last-modified date greater than 1-Jan-2017
zip.MinDate = "2017-01-01T00:00:00Z"

' Also, only unzip files having a last-modified date less than the end of 2020
zip.MaxDate = "2020-12-31T23:59:59Z"

' You don't need to specify both MinDate and MaxDate.
' You can specify only one or the other if needed.

' The MinDate/MaxDate properties apply to all of the Chilkat methods for unzipping.
