SYNTAX​
TIMESTAMP ( arg [ , <format_modifier>, format] )
<format_modifier> ::=

ARGUMENTS​
arg A value to be converted to a timestamp. Valid arguments are numeric, date/time values, and strings. If a format is specified arg must be of type STRING.

format
An optional string argument to specify how the arg should be interpreted.
Return Value​
A time to nanosecond precision of TIMESTAMP data type.
Remarks​
- When the arg is a numeric it is interpreted as the number of nanoseconds since January 1, 1970 UTC.
- The TIMESTAMP datatype has a smaller date range than the DATETIME datatype and should be used as an alternative if more percision is needed.
- If a string is provided and "FORMAT" is not specified, the default format is
"2006-01-02 15:04:05.000000000"
- If "ZONE" is specified, the format must be "UTC" or a location name corresponding to a file in the IANA Time Zone database, such as "America/Los_Angeles".
