As String
You can use the string data type to represent a date or a time stamp. One way to do this is by using ISO 8601 strings, as shown in these examples:
2016-02-15
2015-12-21T17:42:34Z
20150311T122706Z
As Number
You can use the number data type to represent a date or a time stamp. One way to do this is by using epoch time—the number of seconds since 00:00:00 UTC on 1 January 1970. For example, the epoch time 1437136300 represents 12:31:40 PM UTC on 17 July 2015.
