# Time units

> Standard time units used by Palo Alto Networks Cortex XCOR

Palo Alto Networks Cortex XCOR supports a range of standard *time units*:

| Unit | Abbreviation |
| - | - |
| Nanoseconds | `ns` |
| Microseconds | `mu` |
| Milliseconds | `ms` |
| Seconds | `s` |
| Minutes | `m` |
| Hours | `h` |
| Days | `d` |
| Weeks | `w` |
| Months | `M` |
| Years | `y` |

The abbreviations for minutes (`m`) and months (`M`) are case-sensitive.

Additionally, times that use 12-hour clocks designate morning hours with `AM` and
evening hours with `PM`. These abbreviations prefer uppercase and don't use periods.

Certain features, such as
[dashboard time ranges](/navigate/time-ranges), display
only second and larger units and automatically convert units accordingly. For example,
dashboard time ranges automatically convert a manually entered custom time range
of `1ms` to `0.001 seconds`.

Cortex XCOR also automatically converts units in certain display-only
contexts. For example, [dashboard panels](/observe/dashboards/panels) might convert
the numeric values of data points depending on the unit type you designate in a
panel's **Unit <span aria-label="and then">></span> Time** setting and the context
of that value.

If you select the `Nanoseconds` unit, Cortex XCOR interprets a numeric
value of `120` for a data point as 120 nanoseconds and displays it as `120ns`. However,
if you select `Days` as the time unit, Cortex XCOR interprets the same
value as 120 days, converts it to the larger unit of months, and displays it as
`4 months`.
