Feb 11, 2011 · I wonder if the reverse (i.e. TD TIMESTAMP -> Unix timestamp) would be easier, but I haven't put thought into that. At a high level, the code does the following (works for GMT timestamps): - Create a table of reference Unix timestamp (beginning of 2011 in the below), and decides which to use

A PostgreSQL table consists of one or more files of 8KB blocks. The order in which the rows are stored in the file is the physical ordering . You can examine the physical ordering of the rows by selecting the ctid system column: it contains the block number and the item number inside the block, which describe the physical location of the table row.
  • Note: timestamp string must be quoted by either single quote or double quote. Epoch Time: a timestamp value can also be a long integer representing milliseconds since the epoch. For example, the values in the above example can be represented as an epoch 1502535178128 in milliseconds. Please note the epoch time doesn't need any quotes.
  • Convert date to timestamp. To convert date to timestamp, a formula can work it out. Select a blank cell, suppose Cell C2, and type this formula =(C2-DATE(1970,1,1))*86400 into it and press Enter key, if you need, you can apply a range with this formula by dragging the autofill handle. Now a range of date cells have been converted to Unix ...
  • When we create a new object from the Date () class using new Date (), it returns the time in milliseconds when it is created. If we need to get an object from the Date class at a specific point of time, we can pass the epoch timestamp to that class’s constructor. JavaScript. javascript Copy.

    The Year 2038 problem (also called Y2038, Epochalypse, Y2k38, or Unix Y2K) relates to representing time in many digital systems as the number of seconds passed since 00:00:00 UTC on 1 January 1970 and storing it as a signed 32-bit integer.

    Got it - you can use this: =num (date (today (1)))*86400000 - num (date ('1/1/1970'))*86400000. This will give you epoch time in milliseconds for a specified date. Qlik is storing dates as the number of days passed from 1/1/1900, whereas epoch time starts from 1970.
