Occasional TimeoutNegativeWarning: -81612681.54468305 is a negative number.

[peterhirn]

I'm running a Node.js app in K8s. Occasionally (every other day) I get this warning:

(node:1) TimeoutNegativeWarning: -81612681.54468305 is a negative number.
Timeout duration was set to 1.
    at new Timeout (node:internal/timers:195:17)
    at setTimeout (node:timers:138:19)
    at reconnect (file:///app/server/node_modules/postgres/src/connection.js:353:5)
    at Object.connect (file:///app/server/node_modules/postgres/src/connection.js:113:7)
    at connect (file:///app/server/node_modules/postgres/src/index.js:392:7)
    at Query.handler (file:///app/server/node_modules/postgres/src/index.js:336:14)
    at Query.handle (file:///app/server/node_modules/postgres/src/query.js:140:65)

(with varying negative timeout values)

The stacktrace always points to the reconnect function here https://github.com/porsager/postgres/blob/master/src/connection.js#L353

Unfortunately I don't know how to reproduce this issue. On first glance it looks like it happens directly after the app boots up.

We recently update from node 22 to node 24 and from "postgres": "^3.4.5" to "postgres": "^3.4.7" and face the same issue.

I use Bun and got the same issue

But after many times it looks like everything works fine

I don't think there is any negative impact because of this warning, it's just noisy. A simple fix could be

setTimeout(connect, Math.max(closedDate ? closedDate + delay - performance.now() : 0, 0))
