How do you parse a date and time string with offset using NodaTime?

I am trying to learn how to use NodaTime within my application, but cannot find very many examples of how to do certain things with this library.

Using pure NodaTime code, there is not currently a direct parser for an OffsetDateTime. See the documented limitations. However, you can construct one by parsing a LocalDateTime and an Offset separately:

var ldt = LocalDateTimePattern.CreateWithInvariantCulture("yyyy/MM/dd HH:mm:ss")
                              .Parse("2012/08/30 17:45:00")
                              .Value;

var o = OffsetPattern.GeneralInvariantPattern
                     .Parse("-05")
                     .Value;

var odt = new OffsetDateTime(ldt, o);

There is a similar parser for Instant, but it requires a UTC time - not an offset.

You could also just use the text parsing for DateTimeOffset in the BCL, and then do:

var odt = OffsetDateTime.FromDateTimeOffset(dto);

Either way, once you have an OffsetDateTime, it is convertible to an Instant:

var instant = odt.ToInstant();
