I got an e-mail forward later than I expected. So I decided to look in the email header for a time line and ended up looking at timestamps from all the different timezones the e-mail had been. To have easy access to those dates in my own locale, I created a small online tool to translate dates to your local locale:
About the tool
Currently it only supports a small subset of dates. If you find a date that it does not yet match but should or you have a feature request, please consider posting a comment below.
If you want to try the tool, you can use the following example input:
