Treat only 10-digit numeric values as seconds.
Line 180 converts every numeric value below 100_000_000_000 to seconds. Therefore, parseDateSafe(17_243_124_000) converts an 11-digit millisecond timestamp to the wrong date. The string branch correctly treats the same value as milliseconds.
Restrict the seconds conversion to exactly 10-digit values. Add a test for an 11-digit millisecond timestamp.
Proposed fix
- const timestamp = Math.abs(date) < 1e11 ? date * 1000 : date;
+ const magnitude = Math.abs(date);
+ const timestamp = magnitude >= 1e9 && magnitude < 1e10 ? date * 1000 : date;📝 Committable suggestion

Handle all valid numeric timestamp inputs.
The current guards return "" for 0, even though Unix epoch 0 is valid. Numeric Unix-second values are also interpreted as milliseconds, and numeric timestamp strings are not normalized consistently. This can produce incorrect or missing time-ago output.
Update both helpers to distinguish only null, undefined, and empty strings before parsing, normalize millisecond/second numbers and numeric strings consistently, and add regression tests for epoch 0, Unix seconds, and numeric timestamp strings.
Also applies to: 188-190.
