Unix timestamp

1. A Unix timestamp is a numerical value representing the number of seconds that have elapsed since 00:00:00 UTC on January 1, 1970.

2. Unix timestamps are widely used in computer systems, typically measured in seconds, though they can also be expressed in microseconds or milliseconds.

3. On 32-bit systems, the time range represented by a Unix timestamp is approximately from 1901 to 2038. On 64-bit systems, the range is much larger, sufficient to cover the foreseeable future.

4. Current timestamp: The current timestamp is based on the device’s current time and is for reference only!
