1)
./script.ksh runs the (if any) script.ksh in the current directory
sh script.ksh runs the first script.ksh in your PATH using sh (which, for example on Linux would be Bash, on AIX ksh and on Solaris is sh), ignoring the "shebang" line in your script
script.ksh would run the first script.ksh in your PATH using either your default shell (as specified in /etc/passwd, or elsewhere) or whatever you specified in the "shebang"

The interpreter used has nothing to do with the .ksh extension of your filename script.ksh.

2) Yes and yes

NAME
times - shell built-in function to report time usages of the current shell SYNOPSIS
sh times ksh times DESCRIPTION
sh Print the accumulated user and system times for processes run from the shell. ksh Print the accumulated user and system times for the shell and for processes run from the shell. On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways: 1. Variable assignment lists preceding the command remain in effect when the command completes. 2. I/O redirections are processed after variable assignments. 3. Errors cause a script that contains them to abort. 4. Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari- able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation are not performed. ATTRIBUTES
