Developer builds Node.js server to fix LLM timestamp bugs

By PulseAugur Editorial · [1 sources] ·

A developer has created a zero-dependency Node.js server for tsforge-mcp, designed to address timestamp and date-related bugs that large language models often mishandle. The server implements boundary-correct algorithms for complex date calculations, such as cron job scheduling, Excel's 1900 leap year bug, ISO-8601 week numbering, and Daylight Saving Time transitions. It supports dual transport methods, including stdio for local clients like Claude Desktop and Streamable HTTP for remote clients like the ChatGPT Apps SDK, with a public converter available at gotimestamp.com.
