# Use date and time functions in formula expressions
<a name="expression-date-and-time-functions"></a>

In [transforms](transforms.md) and [metrics](metrics.md), you can use the date and time functions in the following ways:
+ Retrieve the current timestamp of a data point in UTC or in the local time zone.
+ Construct timestamps with arguments, such as `year`, `month`, and `day_of_month`.
+ Extract a time period such as a year or month with the `unix_time` argument.


| Function | Description | 
| --- | --- | 
| `now()` | Returns the current date and time, in seconds, in the Unix epoch format. | 
| `timestamp()` |  [See the AWS documentation website for more details](http://docs.amazonaws.cn/en_us/iot-sitewise/latest/userguide/expression-date-and-time-functions.html)  | 
| `mktime(time_zone, year, month, day_of_month, hour, minute, second)` | Returns the input time in seconds, in the Unix epoch format.<br />The following requirements apply for using this function:[See the AWS documentation website for more details](http://docs.amazonaws.cn/en_us/iot-sitewise/latest/userguide/expression-date-and-time-functions.html)<br />The following limits apply for using this function:[See the AWS documentation website for more details](http://docs.amazonaws.cn/en_us/iot-sitewise/latest/userguide/expression-date-and-time-functions.html)<br />Examples:[See the AWS documentation website for more details](http://docs.amazonaws.cn/en_us/iot-sitewise/latest/userguide/expression-date-and-time-functions.html) | 
| `localtime(unix_time, time_zone)` | Returns the year, the day of the month, the day of the week, the day of the year, the hour, the minute, or the second in the specified time zone from the Unix time.<br />The following requirements apply for using this function:[See the AWS documentation website for more details](http://docs.amazonaws.cn/en_us/iot-sitewise/latest/userguide/expression-date-and-time-functions.html)<br />Example response: `2007-12-03T10:15:30+01:00[Europe/Paris]`<br />`localtime(unix_time, time_zone)` isn't a standalone function. The `year()`, `mon()`, `mday`, `wday()`, `yday()`, `hour()`, `minute()`, and `sec()` functions take `localtime(unix_time, time_zone)` as an argument.<br />Examples:[See the AWS documentation website for more details](http://docs.amazonaws.cn/en_us/iot-sitewise/latest/userguide/expression-date-and-time-functions.html) | 
| `year(localtime(unix_time, time_zone)` | Returns the year from `localtime(unix_time, time_zone)`. | 
| `mon(localtime(unix_time, time_zone))` | Returns the month from `localtime(unix_time, time_zone)`. | 
| `mday(localtime(unix_time, time_zone))` | Returns the day of the month from `localtime(unix_time, time_zone)`. | 
| `wday(localtime(unix_time, time_zone))` | Returns the day of the week from `localtime(unix_time, time_zone)`. | 
| `yday(localtime(unix_time, time_zone))` | Returns the day of the year from `localtime(unix_time, time_zone)`. | 
| `hour(localtime(unix_time, time_zone))` | Returns the hour from `localtime(unix_time, time_zone)`. | 
| `minute(localtime(unix_time, time_zone))` | Returns the minute from `localtime(unix_time, time_zone)`. | 
| `sec(localtime(unix_time, time_zone))` | Returns the second from `localtime(unix_time, time_zone)`. | 

## Supported time zone formats
<a name="time-zone-expressions"></a>

You can specify the time zone argument in the following ways:
+ Time zone offset - Specify `'Z'` for UTC or an offset (`'+2'` or `'-5'`).
+ Offset IDs - Combine a time zone abbreviation and an offset. For example, `'GMT+2'` and `'UTC-01:00'`. The time zone abbreviation must contain only three letters.
+ Region based IDs - For example, `'Etc/GMT+12'` and `'Pacific/Pago_Pago'`.
