wishlist: two timestamps

[yarikoptic]

ATM there is only a timestamp which is actually the timestamp for completion of execution. Having both (e.g. "datetime_start", "datetime_end") would allow to report duration of execution and or search up for tasks by their start or end dates/times.

The base executor just runs and then is done, so time stamp is just there to indicate a start time. If a child executor (based off of shell) expects to run longer and needs and end time, that executor would implement it.

I forgot to paste an example:

$> qme run bash -c 'date; sleep 2; date'
Database: sqlite
[shell-00d909b6-2119-4e97-8669-449f6786c8bd][returncode: 0]

$> qme show                             
usage: qme [-h] [--version] [--config_dir CONFIG_DIR] {version,config,clear,exec,generate-key,ls,run,rerun,search,start,get} ...
qme: error: argument command: invalid choice: 'show' (choose from 'version', 'config', 'clear', 'exec', 'generate-key', 'ls', 'run', 'rerun', 'search', 'start', 'get')

# doh -- `git show` and in general `show` keeps me away from `get` which is typically something taxing
$> qme get 
Database: sqlite
{
    "executor": "shell",
    "uid": "shell-00d909b6-2119-4e97-8669-449f6786c8bd",
    "data": {
        "pwd": "/home/yoh/proj/qme",
        "user": "yoh",
        "timestamp": "2020-05-29 15:40:18.690043",
        "output": [
            "Fri 29 May 2020 03:40:16 PM EDT\n",
            "Fri 29 May 2020 03:40:18 PM EDT\n"
        ],
        "error": [],
        "returncode": 0,
        "pid": 2768296,
        "cmd": [
            "bash",
            "-c",
            "date; sleep 2; date"
        ],
        "status": "complete"
    },
    "command": "bash -c date; sleep 2; date"
}

So from

"timestamp": "2020-05-29 15:40:18.690043",
        "output": [
            "Fri 29 May 2020 03:40:16 PM EDT\n",
            "Fri 29 May 2020 03:40:18 PM EDT\n"
        ],

it seems to correspond to end time. Indeed base executor (or jobs "broker" of a kind) could record start time (only) and then specific implementation could report/record end time (some times it would need to be queried from e.g. PBS or alike).

I think this would need to be executor specific, so going to close the issue. The base executor (as we use here) is to be kept as simple as possible.
