Subtract 30 minutes from time value - 2021-05-12T19:30:00

Hi

This seems to return the date as a table.

Code:

* table:
[sec]
  * number: 0
[min]
  * number: 0
[day]
  * number: 12
[isdst]
  * bool: false
[wday]
  * number: 4
[yday]
  * number: 132
[year]
  * number: 2021
[month]
  * number: 5
[hour]
  * number: 19

How can I convert this back to a string in the same format as the original time (ie: 2021-05-12T19:30:00 > 2021-05-12T19:00:00)?

Many thanks
James
