[jira] [Commented] (PDFBOX-2122) FontBox's TTFDataStream doesn't set timezone in readInternationalDate

    [ https://issues.apache.org/jira/browse/PDFBOX-2122?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14020985#comment-14020985 ] 

Tilman Hausherr commented on PDFBOX-2122:
-----------------------------------------

If we change something, do you have a test that can show that the change produces something correct?

Or can you change it yourself locally and test it? I'd change
{code}
GregorianCalendar cal = new GregorianCalendar(1904, 0, 1);
{code}
to
{code}
Calendar cal = GregorianCalendar.getInstance(TimeZone.getTimeZone("UTC"));
cal.set(1904, 0, 1, 0, 0, 0);
{code}

> TTFDataStream doesn't set the timezone for the calendar. GregorianCalendar defaults to the system's timezone.  This means that people in different timezones will get slightly different dates.  (TIKA-1325).
> One TTF Spec (https://developer.apple.com/fonts/TTRefMan/RM06/Chap6.html) doesn't specify the timezone, but my guess would be UTC...except that it is Apple, so maybe it's Cupertino. :)
