# `gtime`, `ltime`

_Global and local time_


## `gtime`

_UTC equivalent of local timestamp_
```syntax
gtime ts    gtime[ts]
```

Where `ts` is a datetime/timestamp, returns the UTC datetime/timestamp.
```q
q).z.p
2009.10.20D10:52:17.782138000
q)gtime .z.P                      / same timezone as .z.p
2009.10.20D10:52:17.783660000
```


## `ltime`

_Local equivalent of UTC timestamp_
```syntax
ltime ts    ltime[ts]
```

Where `ts` is a datetime/timestamp, returns the local datetime/timestamp.
```q
q).z.P
2009.11.05D15:21:10.040666000
q)ltime .z.p                  / same timezone as .z.P
2009.11.05D15:21:10.043235000
```


## System clocks

UTC and local datetime/timestamps are available as


scope   datetime     timestamp
\------------------------------
UTC     [`.z.z`](dotz.md#zz-utc-datetime)         [`.z.p`](dotz.md#zp-utc-timestamp)
local   [`.z.Z`](dotz.md#zz-local-datetime)         [`.z.P`](dotz.md#zp-local-timestamp)
