# tf - CLI Unix Time formatter
`tf` scans for UNIX epoch times in input and outputs them
as human readable strings to stdout.
```
$ cat log.txt
[1524241219] Time is on my side
[1555777220] Yes it is
[1587399621] A time in epoch millis: 1637419929123
[1618935621] A time in epoch nanos: 1637419929123456789
$ tf -g log.txt
[12:20:19] Time is on my side
[12:20:20] Yes it is
[12:20:21] A time in epoch millis: 09:52:09.123
[12:20:21] A time in epoch nanos: 09:52:09.123456789
```
## Usage
```
$ tf --help
usage: tf [file1 [file2 [...]]]
UNIX Time Formatter (tf)
Scans for UNIX epoch times in input and outputs them
as human readable strings to stdout.
10-digits are interpreted as seconds, 13 as milliseconds,
16 as microseconds, and 19 as nanoseconds.
If no filenames or only '-' is passed, stdin is processed.
examples:
$ echo 1637421447 | tf
$ tf -g log.txt | head
The time formatting uses Golang Time.Format layouts:
https://pkg.go.dev/time#Time.Format
options:
-b, --block use block buffering (default: line buffering)
-z, --block-size uint32 block buffer size (default 4096)
-d, --date output with date, same as --format '2006-01-02 15:04:05'
-f, --format string output with Golang Time.Format layout (default: '15:04:05')
-g, --global global match (default: convert only first match in line)
-h, --help show help
```

## Example Usage
Raw log:
```
$ cat log.txt
[1524241219] Time is on my side
[1555777220] Yes it is
[1587399621] A time in epoch millis: 1637419929123
[1618935621] A time in epoch nanos: 1637419929123456789
```
Basic usage, piping from `stdin`:
```
$ cat log.txt | tf
[12:20:19] Time is on my side
[12:20:20] Yes it is
[12:20:21] A time in epoch millis: 1637419929123
[12:20:21] A time in epoch nanos: 1637419929123456789
```
Date conversion:
```
$ tf -d log.txt
[2018-04-20 12:20:19] Time is on my side
[2019-04-20 12:20:20] Yes it is
[2020-04-20 12:20:21] A time in epoch millis: 1637419929123
[2021-04-20 12:20:21] A time in epoch nanos: 1637419929123456789
````
Global match, converting sub-second times:
```
$ tf -gd log.txt
[2018-04-20 12:20:19] Time is on my side
[2019-04-20 12:20:20] Yes it is
[2020-04-20 12:20:21] A time in epoch millis: 2021-11-20 09:52:09.123
[2021-04-20 12:20:21] A time in epoch nanos: 2021-11-20 09:52:09.123456789
```
