System Date and Time

Description

Returns a character string of the current system date and time.

Usage

date()

Value

The string has the form "Fri Aug 20 11:11:00 1999", i.e., length 24, since it relies on POSIX's ctime ensuring the above fixed format. Timezone and Daylight Saving Time are taken account of, but not indicated in the result.

The day and month abbreviations are always in English, irrespective of locale.
