An Important Note About Maintenance
Due to the ever-changing nature of timezone data, it is critical that you always use the latest version of this package. Any releases to this project's dependency of moment-timezone will also cause a new release in this package. If you use old versions, there will be a few edge cases where the calculated time is wrong. If you use greenkeeper, please be sure to specify an exact target version so you will always get PR's for even patch-level releases.
