Subject: [PATCH 1/7] tools/psl.c: Fix logic fallout and warning
In the previous update to tools/psl.c, I neglected to see the return type of
localtime_s() and the difference in what value to expect for a successful call.
Use macros instead to remedy this.
Thanks to vtorri for pointing this out in issue #201.
Fixes: #201.
