NH data files seem to have a YYYY-MM-DD timestamp format while other states' jurisdictions use a full timestamp. For example nh/atkinson/people.yml contains updated_at values like:
nh/atkinson/people.yml
15: updated_at: '2025-06-06'
29: updated_at: '2025-06-06'
43: updated_at: '2025-06-06'
57: updated_at: '2025-06-06'
71: updated_at: '2025-06-06'
Another example
nh/pembroke/people.yml
15: updated_at: '2025-06-06'
29: updated_at: '2025-06-06'
43: updated_at: '2025-06-06'
57: updated_at: '2025-06-06'
71: updated_at: '2025-06-06'
Broke my attempt to parse through the full data set :)
