Nomad uses time.LoadLocation() to translate a periodic job time zone string value to a time.Location. From godocs:

LoadLocation looks for the IANA Time Zone database in the following locations in order:

* the directory or uncompressed zip file named by the ZONEINFO environment variable
* on a Unix system, the system standard installation location
* $GOROOT/lib/time/zoneinfo.zip
* the time/tzdata package, if it was imported

So non-Unix systems require Go to be installed or time/tzdata to be imported, otherwise running periodic jobs with a specific time_zone value results in an error:

Invalid time zone "America/Toronto": unknown time zone America/Toronto

This commit adds the timetzdata build tag on Windows to embed the time zone data into the final binary. This results in a slightly bigger binary, but from time/tzdata godocs:

Importing this package will increase the size of a program by about 450 KB.
[..]
This package will be automatically imported if you build with -tags timetzdata.

Closes #18578
