STRFTIME — Formats the date and time
Returns the current date/time in a specified format.
STRFTIME
passes the
epoch
and format
arguments directly to the underlying strftime(3)
C library call, so check out that
manpage for more information. The timezone
parameter should be the name of a directory/file in /usr/share/zoneinfo
(e.g., America/Chicago
or America/New_York
).
