[Lucene.Net] [jira] [Commented] (LUCENENET-409) Invalid Base exception in DateField.StringToTime()

["Neal Granroth (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LUCENENET-409?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13020468#comment-13020468 ] 

Neal Granroth commented on LUCENENET-409:
-----------------------------------------

I looked at the patch.  It will clear the exception, but DateField will not work correctly.

The StringToDate() method does not apply the reverse of the TicksToMilliseconds conversion which the DateToString() method applied.  Also, the StringToDate() method does not apply the reverse of the UTC offset which the DateToString() method applied.

Would you prefer separate JIRA issues for these?

> The Lucene.Net.Documents.DateField.StringToTime() method called by StringToDate() appears to specify an invalid value for the base in the .NET Convert.ToInt64() call.  When a DateField value in a legacy index is read, or Lucene.NET 2.9.4 is used with legacy code that relies upon DateField, the following exception occurs whenever StringToDate() is called:
> System.ArgumentException: Invalid Base.
>    at System.Convert.ToInt64(String value, Int32 fromBase)
>    at Lucene.Net.Documents.DateField.StringToTime(String s)
>    at Lucene.Net.Documents.DateField.StringToDate(String s)
