ZenQL search – relative time period

Created by r.saunders, last modified by r.bromley on 13 Feb 2022

A relative time period is a token that can convert a date and time value, relative to the current date and time (UTC). It can be used in an operator or as a parameter of a date time function.


The token consists of 1 or more space-delimited segments and can optionally contain a preceding plus or minus sign. The sign can only be used once and is applied to the whole expression. When combining segments, there is no need enclose them in double quotes.

    [- | +]<segment>[ <segment> ...n]
