An absolute time. No literal syntax is provided for the TIME type; instead, see the std.time function for creating a TIME value:

declare local var.t TIME;
set var.time = std.time("Fri, 21 Aug 1981 14:51:07 GMT", now);

Conversions to STRING values are rendered in RFC 1123 format, with the timezone in GMT:

declare local var.t TIME;
set var.t = std.time("Thu, 01 Jan 1970 00:00:00 GMT", now);
set resp.http.X-t = var.t; /* "Thu, 01 Jan 1970 00:00:00 GMT" */

Similar to RTIME values, a TIME value is a 64-bit signed integer, measured in nanoseconds since epoch.
