## Methods

### Standard methods

- new

  - fromText

  - toText

  - sort

  ### Writing methods

- set\_Created ($date, $release)

  - set\_AnnotationUpdate ($date, $release\[, $version\])

  - set\_SequenceUpdate ($date, $release\[, $version\])

  ## TRANSITION

The format of the DT line will change in early 2004 from:

```
 DT   01-JUL-1993 (Rel. 26, Created)
 DT   01-JUL-1993 (Rel. 26, Last sequence update)
 DT   28-FEB-2003 (Rel. 41, Last annotation update)
```

to:

```
 DT   01-JUL-1993, integrated into UniProtKB/Swiss-Prot.
 DT   01-JUL-1993, sequence version 36.
 DT   28-FEB-2003, entry version 54.
```

This module supports both formats. To convert an entry from the old to the new format, do:

```
 $entry->DTs->CREATED_rel("UniProtKB/Swiss-Prot");
 $entry->DTs->ANN_version(54);
 $entry->DTs->SQ_version(36);
```
