We can confirm the aforementioned by querying a test table with a column for each of the aforementioned formats. To read dates you must use one of the following formats: While there's a Prisma issue about ISO 8601 support, it's been open for years. The RFC also allows the "T" to be replaced by a space (or other character), while the standard only allows it to be omitted (and only when there is agreement between all parties using the representation). For example truncated representations of years with only two digits are not allowed - RFC 3339 requires 4-digit years, and the RFC only allows a period character to be used as the decimal point for fractional seconds. The RFC also has some small, subtle differences. We can use the s format string substitution to return the number of seconds since 00:00. The STRFTIME() function returns a date and time value in the specified format. SQLite provides us with a couple of ways to get the unix timestamp. Most notably RFC 3339 specifies a complete representation of date and time (only fractional seconds are optional). The unix timestamp is the number of seconds since 00:00:00 UTC. Pretty much, yes - RFC 3339 is listed as a profile of ISO 8601. Prisma also supports an SQLite TEXT datatype, however the format must be in either the RFC 3339 or RFC 2822 formats, which SQLite does not support, instead favoring ISO-8601.Īs it happens, ISO-8601 is substantially similar to, but not identical to RFC 3339: To account for this, Prisma reads and writes the NUMERIC datatype for its DateTime support. ![]() ![]() Which format you use, is entirely up to your application. The built-in date and time functions of SQLite understand date/times in all of the formats above, and can freely change between them.
