The Omega Server and Omega Server Gateway use pseudo Julian dates we refer
to here as "Omega Julian" dates that are in error with respect to true
Astronomical Julian dates by 2,415,019 days. That would cause dates to be
in error by more than 6,612 years, except reciprocal errors are made in
conversion from Gregorian to Julian and back from Julian to Gregorian, so no
net error results.

Omega's software converts incoming Gregorian dates from real-time data feeds
or historic ASCII price files to "Omega Julian" dates for internal program
use. It converts the internal "Omega Julian" dates back to Gregorian dates
whenever dates are displayed to users. No provision has been made to use
incoming data that has true Astronomical Julian dates, "Omega Julian" dates,
or four-digit year Gregorian dates. Those capabilities would be simple to
provide. Omega simply hasn't provided them. Omega's software assumes all
incoming dates are two-digit year Gregorian dates. It attempts to convert
them to "Omega Julian" dates whether they actually are two-digit year
Gregorian dates or not.

Yes. A simple change needs to be made to the code so that doesn't happen.

I don't know anything about MYM, but from what you say, I don't think there
is much in common with TradeStation or SuperCharts year 2000 issues.

Yes, although different patches would be required for each version of each
program.

Maybe. Others have asked the same question. We are discussing some
considerations. I will post an answer later today.
