function::task_time_string - Linux

Overview

The task_time_string command is used to convert a timestamp, typically obtained from the Linux kernel, into a human-readable string. This string represents the time elapsed since a specific point in the past, known as the epoch, which is January 1, 1970, at 00:00:00 Coordinated Universal Time (UTC). The command is particularly useful for displaying timestamps in a more readable format, such as in log files or user interfaces.

Syntax

task_time_string [timestamp]

• timestamp: (Optional) The timestamp to be converted. If not specified, the current time will be used.

Options/Flags

None.

Examples

To convert the current timestamp to a string:

task_time_string

Output:

2023-03-08 16:27:34

To convert a specific timestamp (in seconds since the epoch):

task_time_string 1678310854

Output:

2023-03-08 16:27:34

Common Issues

• Incorrect timestamp: Ensure that the provided timestamp is accurate and in the correct format (seconds since the epoch).
• Invalid characters: The resulting string may contain characters that disrupt certain formatting or parsing tools.

Integration

The task_time_string command can be integrated into shell scripts or custom programs to handle timestamps. For example, it can format timestamps for display in logs or user interfaces.
