在RoR中解析.Net日期格式

Question

I am currently calling an external API and getting a JSON response. The data has 2 date fields that I need to parse and display in a table in my app.

The issue I am having is that the dates are in .Net format:

/Date(1377183028730-0400)/

Any suggestions on how I can parse this into a usable RoR format?

Answer 1

That looks like a number of milliseconds from an epoch.

You could extract the first part with a regular expression such as

if date =~ /Date\((\d+)-(\d+)\)/
  Time.at($1.to_i/1000.0)
end

The latter part might be a timezone indicator.

Answer 2

Try using Ruby's strptime function . Have a look in the strftime function docs for an explanation of the directives that can be used.
