+## Only ship the Timezones you use.
+
+Time zone information for the whole world is slightly more then a megabyte. But for most applications support every world time zone from 1970 to 2060 is a bit much. You can easily cut down the data generated by running the generate tool:
+
+```
+generate json --startYear:2010 --endYear:2030 --includeOnly:"utc,America/Los_Angeles,America/New_York,America/Chicago,Europe/Dublin"
+```
+
+To just a couple of kilobytes. This is really important for JS backend where you ship the information to the clients.
