We have a high load at weekends:

I think value of data['timestamp'] is not updating at weekends and we try to update the whole data again and again… until there is Monday with the new timestamp.

Probably, gem should check File.mtime for stale? method.

@AlexWayfer Thanks for the bug report. I'll look into it.

@AlexWayfer Checking mtime isn't as simple as it sounds because the gem may not be configured to cache the results in a file. A better solution may be to record when the data was last fetched from the API rather than relying on the timestamp within the data. I'll think about it and patch it soon.

OK, I got it. I think, you're right.

I updated this and release 0.4.0 which fixes the issue.
