@mukundakatta/timestamp-mcp v0.1.0
Install: npm install @mukundakatta/timestamp-mcp Entry: dist/server.js (stdio) Tools: 1 — convert
Tool: convert
Parse any timestamp format and return a normalized UTC breakdown.
Parameters:
input(string|number, required) — Date string (ISO 8601, RFC 2822/3339, natural date) or unix timestamp (seconds if < 10^11, milliseconds otherwise). String digits also accepted.
Returns:
{
"iso": "2026-06-14T12:30:00.000Z",
"unix_ms": 1781440200000,
"unix_s": 1781440200,
"year": 2026, "month": 6, "day": 14,
"hour": 12, "minute": 30, "second": 0,
"weekday": "Sunday"
}Key gotchas
- Output is ALWAYS UTC — no timezone conversion. If you pass
2026-06-14T15:30:00+03:00, you get12:30:00Z(correctly normalized to UTC). - Natural date strings get local-TZ offset applied —
"June 14, 2026"returns June 13, 21:00 UTC (not June 14, 00:00 UTC) if the server's local timezone has a positive offset. Use ISO 8601 for unambiguous dates. - Unix seconds vs milliseconds threshold is 10^11 —
1781712600= seconds,1781712600000= milliseconds. Both numeric and string inputs follow this rule. - Pre-epoch (negative) timestamps work —
-86400correctly returns1969-12-31T00:00:00.000Z(Wednesday). - Fractional seconds preserved —
12:30:00.123Zretains.123in the ISO output andunix_msincludes the 123. - Weekday always included and correctly calculated (epoch zero = Thursday, verified).
- Invalid inputs give clear errors —
"not a date"→convert failed: unparseable input: "not a date"(not an exception). - First 2 calls ~63-69ms (JIT warmup), subsequent calls 2-15ms. p50 = 8ms.
- Date-only strings (
"2026-06-14") default toT00:00:00.000Z(midnight UTC). - Server prints startup banner
timestamp MCP server v0.1.0 ready on stdioto stderr (does not affect MCP protocol).
Tested: 15 calls, 13 success + 2 correct rejections (invalid input, empty string), p50=8ms
