TZ gets set when opening a cygwin terminal. What I'm oberving is strange.. when TZ is set, even if it's set to the same thing as the system time zone, it seems to result in files showing with different mtimes than when TZ is not set. When TZ is not set, the system time zone is used. Anyway, once getCurrentTimeZone is fixed, I'll want to have TZ not set so changes to the system time zone are available immediately.

{- On Windows, if HOME is not set, probe it and set it.
|
|
- This is a workaround for some Cygwin commands needing HOME to be set,
|
|
- and for there being no known way to set environment variables on
|
|
- Windows, except by passing an environment in each call to a program.
|
|
- While ugly, this workaround is easier than trying to ensure HOME is set
|
|
- in all calls to the affected programs.
|
|
-
|
|
- If TZ is set, unset it.
|
|
- TZ being set can interfere with workarounds for Windows timezone
|
|
- horribleness, and prevents getCurrentTimeZone from seeing the system
|
|
- time zone.
|
|
-
|
|
- Due to Windows limitations, have to re-exec git-annex with the new
|
|
- environment.
