<p>De/serialize timestamps as seconds since the UNIX epoch.
Subsecond precision is <em>only</em> supported for <a href="struct.TimestampSecondsWithFrac.html" title="struct serde_with::TimestampSecondsWithFrac"><code>TimestampSecondsWithFrac</code></a>, but not for <a href="struct.TimestampSeconds.html" title="struct serde_with::TimestampSeconds"><code>TimestampSeconds</code></a>.
You can configure the serialization format between integers, floats, and stringified numbers with the <code>FORMAT</code> specifier and configure the deserialization with the <code>STRICTNESS</code> specifier.</p>
<p>The <code>STRICTNESS</code> specifier can either be <a href="formats/struct.Strict.html" title="struct serde_with::formats::Strict"><code>formats::Strict</code></a> or <a href="formats/struct.Flexible.html" title="struct serde_with::formats::Flexible"><code>formats::Flexible</code></a> and defaults to <a href="formats/struct.Strict.html" title="struct serde_with::formats::Strict"><code>formats::Strict</code></a>.
<a href="formats/struct.Strict.html" title="struct serde_with::formats::Strict"><code>formats::Strict</code></a> means that deserialization only supports the type given in <code>FORMAT</code>, e.g., if <code>FORMAT</code> is <code>i64</code> deserialization from a <code>f64</code> will error.
<a href="formats/struct.Flexible.html" title="struct serde_with::formats::Flexible"><code>formats::Flexible</code></a> means that deserialization will perform a best effort to extract the correct timestamp and allows deserialization from any type.
For example, deserializing <code>TimestampSeconds&lt;f64, Flexible&gt;</code> will discard any subsecond precision during deserialization from <code>f64</code> and will parse a <code>String</code> as an integer number.</p>
<p>This type also supports <a href="::chrono_0_4::DateTime"><code>chrono::DateTime</code></a> and <a href="::chrono_0_4::NaiveDateTime"><code>chrono::NaiveDateTime</code></a> with the <code>chrono</code>-<a href="https://docs.rs/serde_with/2.3.3/serde_with/guide/feature_flags/index.html">feature flag</a>.
This type also supports [<code>time::OffsetDateTime</code>][::time_0_3::OffsetDateTime] and [<code>time::PrimitiveDateTime</code>][::time_0_3::PrimitiveDateTime] with the <code>time_0_3</code>-<a href="https://docs.rs/serde_with/2.3.3/serde_with/guide/feature_flags/index.html">feature flag</a>.</p>
<p>This table lists the available <code>FORMAT</code>s for the different timestamp types.
The <code>FORMAT</code> specifier defaults to <code>i64</code> or <code>f64</code>.</p>
