DateTime.Now.AddDays(-1) throw Npgsql.PostgresException

See original GitHub issue

This always works

DateTime changedAfter = DateTime.Now.AddDays(-1);

await _context.Entity
    .Where(e => e.Updated > changedAfter)
    .ToListAsync();

My understanding is that your translater now translate a specific DateTime, which always works.

This throws exception on a certain environment

Getting an exception on linux docker container (microsoft/dotnet:2.2.2-aspnetcore-runtime) in english/utc timezone with Npgsql.EntityFrameworkCore.PostgreSQL 2.2.0, with Microsoft.AspNetCore.App 2.2.2.

Strangly enough, it dont throw an exception on my development environment which is windows 10, norwegian/utc+2 timezoned. Against the same database with the same runtime version.

await _context.Entity
    .Where(e => e.Updated > DateTime.Now.AddDays(-1))
    .ToListAsync();

My understanding is that now you are translating AddDays(-1), which fails.

Thanks for an otherwise very stable/reliable implementation of EF Core!

a slightly related thing, the actual character in the source code file may also matter depending on the encoding of the file it is difficult to figure out the difference.

@Andrioden just to be clear, even if the fix we pushed doesn’t address your issue, it’s still important - there are various other culture-related bugs that it prevents.

@austindrenski are you able to continue investigating this?
