As I can read on https://nodatime.org/2.0.x/userguide/migration-to-2 the support for numeric formatting of Instants has been removed.
Is there currently a way to create a NodaPatternConverter that will convert to a unix / ticks format and back?
SystemClock.Instance.GetCurrentInstant().ToString( "d", CultureInfo.InvariantCulture );
Results in the following exception:
NodaTime.Text.InvalidPatternException : The standard format "d" is not valid for the NodaTime.Instant type.
Well, you can implement
IPattern<T> yourself. Your parser would just need to use
long.Parse then call
Instant.FromUnixTicks. The formatter would just need to call
Instant.ToUnixTimeTicks and format the result. Ideally, do both of those in the invariant culture.
You can then pass that pattern to the
NodaPatternConverter<T> constructor - or just implement
JsonConverter directly, to be honest.
Note that this will only give you tick resolution, which matches 1.x but may lose data with 2.x values.
I'd strongly encourage you to move away from this format as soon as you can though.
