Specifying a literal time or datetime value
When specifying a literal time or datetime value for time/datetime, you are restricted to the formats in the table below, and you must enclose the value in backquotes – for example, `20141231 235959`.
Do not use any separators such as slashes (/) or colons (:) between the individual components of dates or times.
-
Time values – you can use any of the time formats listed in the table below. You must use a separator before a standalone time value for the function to operate correctly. Valid separators are the letter 't', or the letter 'T'. You must specify times using the 24-hour clock. Offsets from Coordinated Universal Time (UTC) must be prefaced by a plus sign (+) or a minus sign (-).
-
Datetime values – you can use any combination of the date, separator, and time formats listed in the table below. The date must precede the time, and you must use a separator between the two. Valid separators are a single blank space, the letter 't', or the letter 'T'.
