In your query, 2010-4-01 is treated as a mathematical expression, so in essence it read (2010 minus 4 minus 1 is 2005 Converting it to a proper datetime, and using single quotes will fix this issue.) Technically, the parser might allow you to get away with it will do the conversion for you, but in … Read more
SQL Server’s TIMESTAMP datatype has nothing to do with a date and time! It’s just a hexadecimal representation of a consecutive 8 byte integer – it’s only good for making sure a row hasn’t change since it’s been read. You can read off the hexadecimal integer or if you want a BIGINT. As an example: The result is In newer … Read more
Append ‘UTC’ to the string before converting it to a date in javascript:

Short answer: Explanation: (based on this question about LocalDate) Despite its name, java.util.Date represents an instant on the time-line, not a “date”. The actual data stored within the object is a long count of milliseconds since 1970-01-01T00:00Z (midnight at the start of 1970 GMT/UTC). The equivalent class to java.util.Date in JSR-310 is Instant, thus there are convenient methods to provide the conversion to and fro: … Read more
Etc/UTC is the time zone whose display name is UTC. That is, they’re long and short names for the same timezone, per IANA’s time zone database.
You can use datetime.combine(date, time); for the time, you create a datetime.time object initialized to midnight.
What you missed here is timezones. Presumably you’ve five hours off UTC, so 2013-09-01T11:00:00 local and 2013-09-01T06:00:00Z are the same time. You need to read the top of the datetime docs, which explain about timezones and “naive” and “aware” objects. If your original naive datetime was UTC, the way to recover it is to use … Read more
Use to_datetime, there is no need for a format string the parser is man/woman enough to handle it: To access the date/day/time component use the dt accessor: You can use strings to filter as an example:
Turns it into a time value Gives you the seconds since $var Will check if $var has been within the last day.
