date: Does not accept decimal offsets

[waveform80]

Discovered while testing the motd scripts in Ubuntu questing under rust-coreutils. Under gnu-coreutils:

$ gnudate -d "now - 20 seconds" +%s
1757632916
$ gnudate -d "now - 20.1 seconds" +%s
1757632918

Under rust-coreutils:

$ date -d "now - 20 seconds" +%s
1757632958
$ date -d "now - 20.1 seconds" +%s
date: invalid date 'now - 20.1 seconds'

This issue has been fixed in the latest version of parse_datetime.

See https://github.com/uutils/parse_datetime/blob/a4c29bafcb1529d172ace3dacb8db2213a49fbb4/src/items/relative.rs#L141

The example from @waveform80 still fails on main with the most recent parse_datetime version (0.13.1):

$ cargo run -q date -d "now - 20.1 seconds" +%s
date: invalid date 'now - 20.1 seconds'

The problem was the space, in fact date -d "now+1.0 seconds" +%s works fine.

Fixed in uutils/parse_datetime#246
