[Bug 11713] New: Display of Moon phases erratic in app o/p

http://bugs.winehq.org/show_bug.cgi?id=11713

Summary: Display of Moon phases erratic in app o/p
           Product: Wine
           Version: 0.9.56.
          Platform: PC
               URL: http://wxtide32.com/
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

WXTide32 presents data in four different formats, three of which can optionally
show the Moon's current phase (important in understanding tide levels and
currents).  At least two formats, realtime and graph, do not display the phases
(shown as a small circle, divided between black and white, depending on the
computed phase for the date of the data displayed), while the third format,
overview, does show phases.  Cycling the check box, in preferences for each
display format, has no effect on the missing information.  It should be noted
that, on one or two rare occasions, the "moon circle" has been in seen in the
realtime display, but its appearance is not repeatable.  At most, this
appearance suggests that WXTide32 is at least capable of drawing the symbol. 
Resolving why it is not done regularly "is left as an exercise for the
student".

No stdout or stderr messages are generated during testing.

The phases display has been seen in the graph format, too, by scrolling back or
forward about a week.  As the realtime display cannot be scrolled, until one of
the dates with a phase display in it is reached, this cannot be verified in the
realtime format.  I appears the Moon display may, in fact, be working in some
measure.

That's the good news.  The bad news is the displayed phases of the Moon are out
of phase (pun intended) and lag reality by about a week.  That is, on 21 Feb.
2008, there was a full moon but WXTide32 under Wine shows this as a first
quarter moon.  WXTide32 under WinXP correctly shows this as a full moon.  Date
stamps are shown in the tide display and are correct (that is, a Moon symbol is
shown on 21 Feb. under Wine and WinXP, but it is approximately 1 week behind
the real Moon, and WXTide32 under WinXP).

Under Wine 0.9.57, the problem of incorrect phases of the Moon appears
resolved.  Comparison of displayed phases in WXTide32 and other tide predictors
agrees within at least a day (with the range of computational error for simple
tide prediction programs - typically due to, in effect, rounding error).  As
the magnitude of the reported problem was on the order of a week and it's now
in the range of simple computational error, the problem is considered fixed and
resolved.
