Sigh. The xcall recursion after waiting is pointless. Fixed. It was left from testing when i did one second steps (i did after running in an octal problem which resulted in the "10#$s" you can see above, and i have an on-paper TODO for a "decimal" modifier for `if' and `vexpr' because the above would fail if "$s" has leading whitespace). (Btw. i also fixed "vexpr trim" which does not trim at the end in the current release because we allow shorthands like "trim-e" to mean trim-end, and at some time i messed that up since of course "trim" is a valid shorthand for "trim-xy", is it. Lots of sighs here.) |I think some timezones can be 30 minutes off the hour so it may still be |42 minutes from the recipient's point of view?
