Use ctime_r() for the error.log timestamp string rather thean timestr() -

this insures:
1. the timestamp always includes the seconds
2. the tiemstamp is always in 24-hour format (no am/pm indication)

For systems that are configured (in SCFG) for "Military" (24 hour) time format,
the error.log timestamps should appear the same as before.
