How to Calculate Job Duration on LinkedIn Profiles for Enriching Emails

Happy New Year to the amazing Clay team! I'm looking to enrich my email with the latest job duration on Linkedin profiles. The issue is that it captures the "start date" which doesn't correspond to the Linkedin duration (when start date is on the 1st, it returns 1 month less than the actual duration, when start date is on the 31st,30th,28th, the result is 2 months less than the actual duration). I'm using Claygent (AI Web Scraper) + a formula to convert the result for "start date" to a duration (ex. 2 years and 3 months). I tried to prompt it but didn't work. Maybe I should just scrape the duration with AI (but it burns openAI credits...) Any ideas?
