+This example uses kubernetes.utils.duration to parse and display
+a GEP-2257 duration string (you can find the full specification at
+https://gateway-api.sigs.k8s.io/geps/gep-2257/).
+
+Good things to try:
+>>> python examples/gep2257.py 1h
+Duration: 1h
+>>> python examples/gep2257.py 3600s
+Duration: 1h
+>>> python examples/gep2257.py 90m
+Duration: 1h30m
+>>> python examples/gep2257.py 30m1h10s5s
+Duration: 1h30m15s
+>>> python examples/gep2257.py 0h0m0s0ms
+Duration: 0s
+>>> python examples/gep2257.py -5m
+ValueError: Invalid duration format: -5m
+>>> python examples/gep2257.py 1.5h
+ValueError: Invalid duration format: 1.5h
