 The above will work only with GNU `date`. See the POSIX shell example on how to support BSD date variants.
 
+#### Alternative version
+
+You could also use Python (or similar) to generate the formatted date:
+
+```meson
+python = import('python').find_installation('python3')
+
+datetime = '''
+import os
+import time
+
+print(time.strftime(
+    "%Y-%m-%d",
+    time.gmtime(int(os.environ.get('SOURCE_DATE_EPOCH', time.time())))
+))
+'''
+
+formatted_date = run_command(python, '-c', datetime, check: true).stdout().strip()
+```
+
+
 ### Dockerfile
 
 The `SOURCE_DATE_EPOCH` argument value is automaticallly propagated from the `SOURCE_DATE_EPOCH` environment value
