It's always best practice to use the sling models. so that you can use more OOTB Apis to get the date and time.

1.2.2.2. Dates
Date formatting supports timezones and localisation. In case internationalisation is also specified (i18n), it will be applied to the formatting pattern and the locale will be passed forward to formatting.
<!--/* Formatting pattern: */-->
${'yyyy-MM-dd' @ format=myDate}
${'yyyy-MM-dd' @ format=myDate, type='date'} <!--/* Forced formatting type */-->
${'yyyy-MM-dd HH:mm' @ format=myDate, timezone='GMT+00:30'} <!--/* Timezone */-->
${'EEEE, dd MMMM yyyy' @ format=obj.date, locale='de'} <!--/* Locale */-->The formatting pattern supports, at minimum, the following letters:
- y - Year. Variants: yy, yyyy
- M - Month in year. Variants: MM, MMM, MMMM
- w - Week in year. Variants: ww
- D - Day in year. Variants: DD, DDD
- d - Day in month. Variants: dd
- E - Day name in week. Variants: EEEE
- a - Am/pm marker
- H - Hour in day (0-23). Variants: HH
- h - Hour in am/pm. Variants: hh
- m - Minute in hour. Variants: mm
- s - Second in minute. Variants: ss
- S - Millisecond. Variants: SSS
- z - General time zone
- Z - RFC 822 time zone
- X - ISO 8601 time zone. Variants: XX, XXX
All other characters from 'A' to 'Z' and from 'a' to 'z' are reserved for future possible use; if needed, they can be escaped using single quotes. Single quotes are escaped as two in a row. Other characters are not interpreted.
Examples
${'yyyy-MM-dd HH:mm:ss.SSSXXX' @ format=obj.date, timezone='UTC'}
${'yyyy-MM-dd HH:mm:ss.SSSXXX' @ format=obj.date, timezone='GMT+02:00'}
${'yyyy-MM-dd HH:mm:ss.SSS(z)' @ format=obj.date, timezone='GMT+02:00'}
${'yyyy-MM-dd HH:mm:ss.SSSZ' @ format=obj.date, timezone='GMT+02:00'}
${'dd MMMM \'\'yy hh:mm a; \'day in year\': D; \'week in year\': w' @ format=obj.date, timezone='UTC'}
${'EEEE, d MMM y' @ format=obj.date, timezone='UTC', locale='de'}
${'EEEE, d MMM y' @ format=obj.date, timezone='UTC', locale='en_US', i18n}will generate the following output for the date 1918-12-01 00:00:00Z
1918-12-01 00:00:00.000Z
1918-12-01 02:00:00.000+02:00

1918-12-01 02:00:00.000+0200
01 December '18 12:00 AM; day in year: 335; week in year: 49
Sonntag, 1 Dez 1918
Sunday, Dec 1, 1918 <!--/* assuming the formatter 'EEEE, d MMM y' will be translated to 'EEEE, MMM d, y' for the 'en_US' locale by
