@mattlewis92 Would this be more likely to be released faster if we merged it to master instead?

Hey @santam85, thanks for taking the time to make this PR! I managed to find a way to make the date adapters in es module format, whilst preserving the commonjs format for anyone that was relying on it so that it won't be breaking. I just released 0.28.17 with the fix, please let me know if that works for you and sorry again about taking so long to get to this! 🙌
