jbang: jbang wrapper generated files have wrong timestamp

I upgraded jbang to 0.45.0 and tried jbang wrapper install. It generated jbang command files but the file timestamp was 80’s.

Also, the file browser is showing same -

Java version -

openjdk version "14.0.2" 2020-07-14
OpenJDK Runtime Environment AdoptOpenJDK (build 14.0.2+12)
OpenJDK 64-Bit Server VM AdoptOpenJDK (build 14.0.2+12, mixed mode, sharing)

I tried in two different folders and had same behavior for generated files.

Let me know if any other information is needed.
