Description of problem
when using a build_dir with ${UNIX_TIME} a folder named "${UNIX_TIME}" is created with the project.checksum
instead it should use the same folder as the rest of the build
Steps to Reproduce
- create a platformio.ini with UNIX_TIME for build dir
[platformio]
build_dir = ${platformio.workspace_dir}\build\${UNIX_TIME}
- build
Actual Results
project checksum is generated into a different folder that doenst take the variable into account correctly
