timestamp.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Introduction to the SQLite unixepoch() function<\/h2>\n\n\n\n<p>The <code>unixepoch()<\/code> function allows you to obtain a unix timestamp that is the number of seconds since <code>1970-01-01 00:00:00 UTC<\/code>.<\/p>\n\n\n\n<p>Here&#8217;s the syntax of the <code>unixepoch()<\/code> function:<\/p>\n\n\n<pre class=\"wp-block-code\" aria-describedby=\"shcb-language-1\" data-shcb-language-name=\"SQL (Structured Query Language)\" data-shcb-language-slug=\"sql\"><span><code class=\"hljs language-sql\">unixepoch(datetime_value,

(Structured Query Language)<\/span> <span class=\"shcb-language__paren\">(<\/span><span class=\"shcb-language__slug\">sql<\/span><span class=\"shcb-language__paren\">)<\/span><\/small><\/pre>\n\n\n<p>In this syntax:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><code>datetime_value<\/code> is the input date or datetime string you want to convert to a unix timestamp.<\/li>\n\n\n\n<li>modifier is an optional argument that changes the behavior of the <code>unixepoch()<\/code> function.<\/li>\n<\/ul>\n\n\n\n<p>The <code>unixepoch()<\/code> function returns an integer representing the number of seconds since 1970-01-01 00:00:00 UTC.<\/p>\n\n\n\n<p>But if you use <code>\"subsec\"<\/code> modifier, the function will return a floating point including a fractional number of seconds.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">SQLite unixepoch() function examples<\/h2>\n\n\n\n<p>Let&#8217;s take some examples of using the SQLite <code>unixepoch()<\/code> function.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1) Basic SQLite unixepoch() function example<\/h3>\n\n\n\n<p>The following example uses the <code>unixepoch()<\/code> function to obtain the number of seconds between <code>1970-01-01 00:00:00 UTC<\/code> and <code>2024-11-04<\/code>:<\/p>\n\n\n<pre class=\"wp-block-code\"

<code>unixepoch()<\/code> function to obtain the number of seconds between <code>1970-01-01 00:00:00 UTC<\/code> and <code>2024-04-11 15:30:20.45<\/code>:<\/p>\n\n\n<pre class=\"wp-block-code\"

class=\"shcb-language__paren\">(<\/span><span class=\"shcb-language__slug\">sql<\/span><span class=\"shcb-language__paren\">)<\/span><\/small><\/pre>\n\n\n<p>In this example, we use the &#8216;<code>subsec<\/code>&#8216; modifier to get the unix timestamp with a fractional of a second.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3) Using the unixepoch() function to get the number of seconds between two dates<\/h3>\n\n\n\n<p>The following example uses the <code>unixepoch()<\/code> function to get the number of seconds between two dates:<\/p>\n\n\n<pre class=\"wp-block-code\"
